For the Battlestar Galactica and its fleet, which is the greater threat: what lies ahead, or what snaps at their heels? Driven into an uncharted storm zone by the pursuing Cylons, the last survivors of the Twelve Colonies discover a vast, mysterious artifact.

With half of the crew haunted by chilling dreams of lost Earth, Commander Adama and Captain Apollo find themselves at odds over their course of action - a conflict that leads the leader of humankind to question if the time has come to pass the torch.

Will Adama entrust the sanctity of the fleet to the next generation... and if so, would they survive the coming massive Cylon attack without his tactical genius?

And finally - the origin of the traitorous Baltar is finally revealed! What kind of man could betray his own species, and how did the Cylons foster his sinister ambition?
