The BAU (Behavioral Analysis Unit), a team of elite FBI agents, has plenty of twisted criminal minds to apprehend this season. Future episodes include a missing girl vacationing in Atlantic Beach, two married couples who are brutally murdered after being forced to have sex, and two Midwestern families with no clear connection to each other who are killed just miles apart.
We pick up moments after the season 5 finale, when the Unsub Flynn kidnapped Spicer's daughter Ellie, leaving Spicer fatally shot, Kristin, his sister badly hurt and Morgan beaten unconscious. The rest of the BAU team struggles to get through the traffic and find Morgan and Spicer in the midst of a city-wide blackout. They reach Morgan and Kristin and with her help, they are able to put more of the profile together about Flynn. Meanwhile Flynn is using Ellie as a ruse to get to his next victims - she tries to escape from him by getting to another house and he is right behind her when they let her in. Since Spicer is always listening to the radio, JJ has the idea of trying to get through to him using the Emergency Broadcast System and to jump through a lot of hoops in figuring out who has the authority to give her access. Flynn forces Ellie to work with him in torturing another family and has her take the son to the closet per his usual MO. What Flynn doesn't know that Ellie discovers is that there's another son in the family. She lets him escape and tells him to run and call the police in every house down the block. When the neighborhood starts to come after him, he escapes with Ellie into the family's car and drives away. The BAU arrives and is able to put more of their profile together. They discover the Ellie is the key - she's who Flynn was after all along. It was his version of being a grandfather and he was going to keep her and continue his delusion. Garcia discovers who he is and updates the team about his childhood and history. JJ finally gains access to the Emergency Broadcast system and breaks through to start talking to Flynn. She gets through to him and he lets Ellie go. He goes into another house and wants Morgan to come in after him. Morgan finds him holding another couple at gunpoint and in the end, Morgan has no choice but to shoot Flynn. Morgan gets back to Ellie and can rest knowing that she is finally safe.
The BAU team is called in when a girl, Kate Joyce, is reported missing while vacation in Atlantic Beach. Her roommates say she never returned to her hotel room after leaving the Sea-crets nightclub with two men, Syd Phillips and Jim Barrett. The town and entire police force believe these two guys did something to Kim but the two guys aren't talking and it's been almost three days - they have only 12 hours left before they're released. Our team comes in to use their master profiling skills and observe the two guys' non-verbal cues to see if they can get something out of them. Through their questioning and an important find by JJ, the team is able to create a more specific timeline that ultimately causes Jim Barrett to slip up. In the final hour, the Coast Guard finds Kate, alive, clinging to a buoy, and reunites her with her family.

It’s not until the third body – that of Minister Louis Hannum – is discovered dead in his truck on the side of the road that the team figures out that the UnSub is actually a young teenage psychopath. The BAU team discovers that he was left at a hospital in Omaha by his fearful mother due to a misunderstanding of a loophole in the state’s safe haven law, which at one point allowed parents to abandon any child under 18 and have them become a ward of the state.
