Season 1 opens with the Cylons in hot pursuit of Battlestar Galactica and the fleet of humans who survived the War introduced in the preceding TV mini-series. Over the course of 13 episodes, there are acts of sabotage, a rebellion, the revelation of Cylon infiltrators that look human, the discovery of Kobol, a return to Caprica and an assasination attempt. Dr. Baltar’s fantasy Number Six adds sexual tension to throughout. All looks grim heading into Season 2.0.
