S1E1 Part 1

Far away in the galaxy, The Twelve Colonies of Man have enjoyed four decades of peace with the Cylons, a race of machines initially designed as laborers. However, after gaining self-awareness, the Cylons revolted and waged war against their creators. Over time, these machines have transformed into biological entities that resemble humans and are determined to eradicate true humans. To achieve their goal, they enlist the help of a human scientist named Gaius, who assists one of their agents, known as #6, in infiltrating the Colonies’ defenses.
