Set before the events of Battlestar Galactica, Caprica follows two rival families - the Graystones and the Adamas - as they grow, compete, and thrive in the vibrant world of the peaceful 12 Colonies, living in a society close to our own. Entangled in the burgeoning technology of artificial intelligence and robotics that will eventually lead to the creation of the Cylons, the two houses go toe-to-toe, blending action with corporate conspiracy and sexual politics.
On the vibrant world of Caprica, in a culture recognizably close to our own, two dynamic families - the Graystones and the Adamas - live separately on opposite ends of society until they are brought together by tragedy.
In the wake of the MAGLEV bombing that killed his daughter, Daniel Graystone plunges himself into work. He tries to figure out why he can only create a single intelligent robot, not understanding that the answer lies within the fact that part of his daughter survived the explosion and is closer to him than he could imagine. Consumed with grief, Amanda Graystone is obsessed with discovering who her daughter really was, and slowly begins piecing together the details of Zoe's life.
Following Amanda's public revelation that their daughter was responsible for the MAGLEV tragedy, the Graystones must face the wrath of angry Capricans. For Daniel, this includes a confrontation with Sam and Joseph Adama, in which Joseph demands that Daniel reunite him with his daughter's avatar -- the essence of his daughter Tamara (Genevieve Buechner), living on in virtual space. Daniel also realizes he can't deal with his grief in private -- this is all going to play out on a public stage.
As the fallout from Zoe's involvement in the MAGLEV bombing grows, Daniel prepares to defend himself and his company on the hugely popular talk show Backtalk with Baxter Sarno. His plan to distance himself from Zoe finds him alienating Amanda, who is still reeling from her own public detractors. As Daniel steps in front of the cameras for show time, Amanda arrives at the studio, with no intention of staying backstage.
The avatar of Tamara Adama wanders V-World, scared, lost, and unaware that she died nearly a month ago in the MAGLEV bombing. Falling in with a group of gamers, Tamara discovers a new side to V-World - New Cap City, a place where people live random lives of violence and crime in search of the game's elusive meaning. Forced into aiding a digital crime spree, Tamara befriends a young gamer, until she discovers a devastating secret that threatens everything she knows.
Rival industrialist Tomas Vergis arrives on Caprica demanding a meeting with Daniel, threatening to reveal proof that Daniel stole the chip that is key the U-87 Cylon and Graystone's military contract. Vergis whirls up a publicity storm that steals the heart of the Caprican public, and surprisingly serves up a friendly offer to Daniel that could save Graystone Industries. But there's a catch to his proposal that could haunt Daniel for years to come.
Still seeking Zoe's Avatar program, Clarice redoubles her efforts to gain Amanda Graystone's confidence in order to find it. Amanda, meanwhile, has been literally haunted by visions of her brother, who died in a car crash several years ago.

Barnabus escalates his war with Clarice and Zoe tries a daring escape.
Graystone is desperate enough to seek a meeting with Joseph Adama and his Guatrau, the head of the "family," offering him partnership in the business of eternal life - the avatar program he had tried so mightily to create with Zoe's chip.
The struggle for the future of the Colonies continues.
Lines of loyalty have been drawn. Where do you stand?
The conflict that orphaned the Adama brothers on Tauron has begun again, and the turmoil has spilled over to Caprica.
