Season 1 picks up where the miniseries left off. After engaging in a losing battle against the Cylons, humanity's last remnants are forced to flee under the protection of their one remaining warship, the outdated Battlestar Galactica. Pursued by the Cylons — some of whom have now taken human form — Commander Adama and President Roslin lead these last remnants of humanity in search of a new home — a planet called Earth.
