"The Last Battlestar Galactica Leads a Rag Tag Fugitive Fleet on a Lonely Quest for a Shining Planet Known as...Earth."

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.
