Set 58 years before 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.

Daniel Graystone, a computer genius, is owner of a large computer corporation that is spearheading the development of artificial intelligence. He and his wife Amanda, who's a brilliant surgeon, are both relentless in their scientific pursuits. The Adama clan is helmed by Joseph Adama, a renowned criminal defense attorney and father of future Battlestar commander William Adama. When tragedy strikes both families, lines are drawn that will determine the fate of the human race.
