The fight to save humanity rages on.
After losing the war against the Cylon robots, the Battlestar Galactica crew speed toward the fabled 13th colony, Earth. Galactica Commander Adama and President Laura Roslin face waning supplies, crushed morale, ... and the credible threat Cylons aboard the ship.
Season Three kicks off at where the previous season ended and sees the Cylons ruling the majority of the surviving humanity, after the disastrous decision to land and set up home on New Caprica. President Boltar enjoys a decadent lifestyle and is a complete stooge of the Cylons who use him to control their human subjects.
