 The Cylon Imperious Leader, determined that no human at all shall survive, orders Baltar's execution after his usefulness is over, but (as retro-actively revealed in the television series version of the film) he is spared at the last moment in order to help the Cylons hunt down the human fleet.After initially escaping the Cylons across a massive starfield called the Nova of Madagon (referred to as such due to its extremely dangerous, hot environment, and Cylon mines), the "Galactica" and the fugitive fleet find brief respite on the resort planet of Carillon, where they hope to find food and fuel for their journey.As much of the fleet's food supplies were contaminated by pluton bombs during the Cylon attack, the fleet is in desperate straits, and must find a food source soon or face starvation.
