Battlestar Galactica (2005 - 2010): Torn

Baltar remains a prisoner within the Cylon fleet, alive only because his captors believe that he can lead them to a new home: Earth. Indeed, hoping to find the mythical planet for himself, Baltar has pinpointed a nebula that might have been a navigation point for the thirteenth tribe on their ancient journey to Earth. The Cylons send a base ship to investigate. Meanwhile, aboard the Galactica, Gaeta deciphers Baltar's abandoned research notes and also locates the nebula. Eager to resume the quest for Earth, Roslin orders Adama to explore it.
