Apollo and Starbuck discover a void in space. Commander Adama is convinced that this void will lead them to the planet Kobol, and orders they go through.

While Commander Adama leads the rag-tag fleet of ships to the planet Kobol, where he hopes to find clues of Earth's location, the Viper pilots contract a disease, making it necessary for the women to take on fighter patrol duties. But the traitor Baltar leads the Cylons in an attack on the Galactica.

A Cylon kamikaze attack leaves the Galactica burning in space, with no way to extinguish the blaze that has trapped Boomer, Athena, and Boxey except a dangerous spacewalk by Apollo and Starbuck.

While the fleet is plagued by glowing lights that constantly fly past them too fast to be followed, Apollo, Starbuck, and Sheba find the remains of a shipwreck, with a mysterious and seemingly all-powerful being named Count Iblis, who helps them capture Baltar.

When Apollo and Starbuck find a primitive sleeper ship carrying a man, a woman, and four children, speculation spreads in the fleet that the people are from Earth.
