Inspired by the top-rated series CSI: Crime Scene Investigation, CSI: Miami is a drama that follows a South Florida team of forensic investigators who use both cutting-edge scientific methods and old-fashioned police work to solve crimes. Horatio Caine, a former homicide detective, heads a group of investigators who work crimes amid the steamy tropical surroundings and cultural crossroads of Miami.
Eric Delko's life hangs in the balance, having been found in the Glades, barely alive. He immediately went into surgery to remove the bullet that remained in his head from the first time he was shot and slips into a coma after it's completed successfully. We flashback to 1997 and how the team came together, with Eric, a salvage truck driver, finding a submerged car with a dead woman inside. He calls Detective Horatio Caine who comes to investigate with the help of Calleigh Duquesne, on her first day at the Special Investigations Unit. Back then, science took a back seat to on foot detective work but with the help of Calleigh, a young tech Natalie Boa Vista and Jesse Cardozo, on his last day, they figure out who was responsible for the murder of the woman. It turns out that she was being stalked by her gardner. Even though her husband looked good for the crime, through blood DNA analysis, Horatio finds a match and can place the gardner with the woman. Eric finally wakes up at the end of the episode with Horatio, Calleigh and the rest of his CSI team by his side.
Jesse Cardoza returns to Miami and the Crime Lab just as a masked man takes it over. The man, calling himself Ted, takes Jesse, the receptionist and two lab techs hostage, asking only to speak to Horatio Caine. When Caine gets there, Ted tells him that he wants justice. He shoots the receptionist and Horatio gets in there and takes her out, discovering that Jesse is there. Matthew directs him to a check cashing place where they should get $100,000 dollars for him. They do so but this turns out to only be a clue from Ted as to the justice he wants. The money is counterfeit and the owner of the check cashing place, Darren Ripley, used to be his business partner and completely bankrupted him and ruined his marriage. The owner identifies Ted as really Matthew Sloan. When he calls Horatio to check up on the fate of Darren, he tells Horatio that he's not finished with getting justice. They discover he's going after his ex-wife, now remarried as Rebecca Arrington. The CSIs remove her, her son and new husband only to find that Matthew still breaks into their house but leaves immediately. Or so they think. Upon investigation, they discover that Rebecca's new husband was actually the one to break down the door to frame Matthew. Jesse also discovers that Matthew lost his son due to accusations of child abuse but they probe and find out, Rebecca was responsible for it. Horatio arrests both Rebecca and her husband and reunites Matthew with his son for one moment before he as well gets taken into custody. Horatio got justice once again.
Three out of four guys playing for a charity volleyball tournament get electrocuted from a current in the sand during the game. Jesse and Calleigh discover an electric cable running beneath the sand and carbon crystals under the court that conducted the electricity. The sole survivor was saved from his rubber soled sand shoes. The tournament was a charity event hosted by Amanda Collins, a rich older woman, who happened to be sleeping with two of the guys. We dive into the world of "cougars" and their "cubs" and one husband especially doesn't like his wife running around so publicly with younger guys.

Calleigh and Delko testify in front of IA and from Calleigh's testimony, they recommend bringing the case before a grand jury. Delko also refers to Calleigh as his "former girlfriend" in his testimony and Calleigh finds out. He ends things with her after telling her he's been suspended.
A Bernie-Madoff type of character, Howard Burgess, is found murdered in the bathroom of his private plane after police are called in when a repo man tries to take it from the airstrip. Having bankrupted hundreds of Miami's citizens, anyone is potentially a suspect. The team questions Howard's wife, Allison, who now is forced to sell designer sunglasses at a kiosk and helplessly watch as the Feds and repo men confiscate everything they own. A joint is found in the bathroom of the plane which casts suspicion onto Howard's son, Daniel. When Jesse and Tripp talk to Daniel, he admits to helping his father escape his house arrest and file off the tracking device ankle bracelet. He and Allison admit there were millions of dollars Howard had stashed away somewhere but they both have no idea where. Horatio and Ryan discover Howard's ledgers but no clue as to where the money is. When Jesse and Calleigh discover Howard was killed with a chain hanging from a winch in the airplane hangar, they also see someone once again in the plane. Jesse grabs him and the guy tells them he's there to seize the property on behalf of the owner, Gary Archer. who owns a fleet of private jets. The team investigates the paperwork from the first repo man and figure out that Allison was the one who hired him in the hopes to get something back they owned. No evidence comes back from the chain but when they look at the toilet again, they discover a contact lens. While Jesse looks for the owner, Horatio finds the car that Howard escaped in with tires slashed. It comes out that his son discovered he was going to flee with the money that was supposed to go back to the investors. He swears to Horatio the only thing he did was slash his tires and is proved innocent when Jesse and Calleigh match the contact lens to Gary Archer, who was just discovered to also be a victim of Howard's money schemes. Ryan, having cracked the code on the ledgers, figures out the money was stashed on the plane and Horatio gets there to find Daniel already there. The truth comes out that Daniel thought he and his father were going to run away together only to find his dad was going to leave him behind and that's why he slashed the car's tires. The police take Daniel away and Horatio encourages Allison to petition the Feds that the found money be given back to Howard's victims.
Jesse helps one of Howard's victims get a job by calling in a favor.
When a girl, Lauren, brought into the ER pale and unconscious, dies from complete organ failure, Alexx Woods believes she was murdered from an unknown poison. The main suspect is her boyfriend, Ethan, who was planning on proposing to her. Horatio and the team test everything in her apartment for any sort of poison. When the boyfriend collapses during Delko's questioning, they discover Lauren was poisoned with a deadly strain of E-coli. The team investigates the restaurant where Ethan and Lauren last ate but are directed to the farm where the produce comes from, as E-coli starts with the grower. Ryan, Jesse and Walter get resistance from the farm but manage to test the crops and come up with nothing. They investigate other methods the strain could have infected the crops and discover everything is controlled by a larger corporation, Bixby Organic Foods. They secretly go back and test the irrigation system and discover the water tests positive for E-coli as it goes right through a manure invested cattle field. They discover the corn that's feeding the cows is a perfect breeding ground for E-coli but when Alexx tells them that Ethan doesn't have an E-coli infection they have to dig deeper as to what the source is. Bixby was growing genetically engineered corn to make easier to digest and Ethan had eaten some of that corn, showing symptoms of botulism and succumbs to it. Horatio confronts the CEO of Bixby but he claims a few deaths is worth feeding an entire nation. Although Horatio can't press charges, he has enough evidence for Ethan's family to file a law suit. Delko is overwhelmed by not being able to save either Lauren or Ethan and leaves the team.

It's here where the team discovers the 2 groomsmen stole the billionaire's limo, not knowing there was a very valuable stolen painting inside. The billionaire sent his security man after them but, in their drug-addled state, they attack him and one of them kills him.

Horatio is called to find a mother's missing daughter. When her car is found near the Glades, the team searches the trees and swamps until they find a severed arm and leg. They identify the arm as belonging to the missing girl, Ashley Tanner, but the leg is discovered to be from an unidentitified Jane Doe that has radioactive sand on it only found in Las Vegas. They get a lead when they find Ashley's credit card has been used recently. Following the trail, they find another girl, Madeline Briggs, who claims she found the card on the side of a hightway. Madeline seems to be a dead end. Meanwhile, Horatio puts a call into Ray Langston who figures out the leg belongs to his missing girl, Samantha Matthews. He travels to Miami where he and Horatio work to find the killer of these girls. To their horror they discover both were seduced by the promise of making it in the world of modeling and exposed to prostitution. What they didn't count on was the fact that the girls were killed by two different men - a professional "rock star" butcher and Ashley's model manager-turned-pimp.

The team finds a puncture in the hose of the power steering which drained all the fluid, making it impossible to drive. Sadly, there was no crime committed. The team also finds a stash of pot underneath the hood. Greg admits to hiding it there and inadvertently punctured a hole in the hose. It was an unfortunate accident that lost two lives - a family without a mother and a sister without a brother.

Our team investigates the murder of a woman, Renee Dorsett, found axed to death with a fire ax then thrown into the elevator shaft of the building where she worked as a receptionist. Renee, considered as the “Office Nazi,” was known for ratting out her fellow employees to her boss. Everyone in the office is now a suspect, forcing our team to investigate each one of them. Dark secrets are revealed as we learn that one employee even lived in the crawl space above Renee’s desk in order to save money.

During the crazy week of spring break week in Miami, our busy CSI’s are called to the scene of three separate murders. Our first victim, Brad Donner, fell from the hotel balcony and was impaled by a statue. Our second victim, Alex Wilkes, was found dead in an industrial size washer at a laundry service facility that the hotel uses to wash their linens. Our third victim, Paul Arnett, was buried standing up and alive in the sand. Brad was pushed off the balcony of the hotel, and while on his way down he was unintentionally hit by a flare gun shot off by a woman in a hotel room trying to ward off a drunk spring breaker who was hitting on her. Paul was buried up to his head at high tide and was at first knocked unconscious from being kicked in the head and then drowned. Alexis was bludgeoned to death with an iron and thrown in the laundry shoot where she was transported with the linen to the laundry service company. Our team questions everyone from the club bouncer to any spring breaker that may have had contact with our victims. Photos on a laptop reveal that our three victims were friends who made Miami their spring break destination. A video from last years Miami spring break reveals footage of Brad having sex with an obese blonde woman all while Alexis and Paul were hiding in the closet. Laughing and stumbling out of the closet, they completely humiliate the girl and later post the video on the internet. Our team goes through the arduous task of eliminating every blonde girl that our trio may have come in to contact with. We ultimately discover that our ugly duckling blonde girl had turned into a beautiful brunette swan and came back for revenge.

Throughout the investigation Patrick’s ghost appears to Calleigh pleading with her to find out who really set his house on fire. We discover at the end of act 2 that Calleigh is in a coma and everything we’ve seen of her throughout the investigation has been a dream. Our angry neighbor, Stephanie Hollister, was being driven completely mad by the ongoing construction noise and sleep deprivation. We discover that the incessant noise drove her to electrocute the plumber whom we find dead and plastered behind some dry wall.

It is a perfect 20th anniversary party at the home of Laura and Chuck, the seemingly perfect couple and their two teenage children Cody, and Alyssa. After the party has come to an end, Laura’s temperament changes to intense anger at the broken light above their garage. Moments later she is brutally murdered in their driveway, and her family members are the suspects. With the help of a mini cam used to video tape the party, the CSI team is able to view the family’s Thanksgiving dinner that they recorded over for the party. We see in the video Laura forcing Alyssa’s head into the dog bowl as punishment for her “eating like an animal” at the table and discover that she is physically and mental abusing her children. Once the kids open up to the team about the abuse, we discover that Cory is terrified as he is going to be alone with his parents, in particular his mother, next year when Alyssa goes to College. In addition we discover that they had a younger brother Bradley, that Laura “accidentally” killed by making him drink lighter fluid as punishment for burning the rug, (which incidentally Alyssa did and never told her mother). At first Chuck confesses to killing Laura, in a desperate attempt to finally protect his children, and then Alyssa confesses. However we learn it is Cory who killed her with Alyssa’s boyfriend’s baseball bat, out of fear of living alone with her when Alyssa goes away to school. The team greatly sympathizes with this abused family, and we don’t know what will be next for them or Cory for having murdered his abusive mother; that is for the Jury to decide. Meanwhile Delko continues his FBI investigation of who is stealing evidence at CSI headquarters, Walter Simmons being the current suspect.
Delko, who is working with Assistant State Attorney Rebecca Nevins, is on his way to meet her to go over the CSI evidence theft case that he’s been secretly working on. Unbeknownst to him, a suspicious Calleigh follows him after she catches him lying to her. A car bomb goes off and kills Rebecca Nevins. The remote controlled bomb is tracked to the car that was parked next to Nevin’s vehicle and it also happens to have come from MDPD impound lot. Relationships sour between the CSI’s and Delko as they realize that they are all suspects. Things get even more complicated when evidence of stolen diamonds are mysteriously traced back to Ryan’s condo. Ryan is taken into custody. The pieces start to fall together when they realize that Sully, retired CSI, commissioned an old criminal to plant a bomb to scare Nevins. Things went terribly wrong as she wasn’t supposed to die. There is a standoff where one of the uniforms behind Horatio shoots Sully. Sully will live but he is a fallen man, much to Horatio’s chagrin. Through further investigation and DNA results it is revealed that Ryan had nothing to do with evidence stealing and he indeed has been set up. There is a dirty cop within CSI. Proven through the same DNA test where traces of bacteria can be linked to specific individual we discover that our evidence thief is none other than IAB Sergeant Rick Stetler who was spearheading the entire investigation.
A serial killer taunts the CSIs by leaving them cryptic hints, and the longer it takes them to decode these puzzles, the higher the death toll rises.
