There's a party on Galactica's flight deck as Flat-Top just had his thousandth landing. Something goes terribly wrong however when a drone accidentally goes off and explodes in a group of pilots. 13 are dead. During the ceremony Kara Thrace starts thinking about her dead fiancée Zak Adama. And those memories even get clearer when Adama orders her to start training new pilots. She seems very uncomfortable in doing so. The favor she did for Zak by letting him pass basic flight seems to bother her more and more. Angrily she stops training pilots after just one day. Meanwhile on Cylon-occupied Caprica Helo and Cylon-Sharon find a bomb shelter in a restaurant. It seems like a good place to stay for a while. There's food, water and anti-radiation medication in abundance.

The fleet is running out of tylium fuel and will soon not have enough to keep running from the Cylons, when they find an asteroid with several years worth of tylium ore...unfortunately, the Cylons have already built a mining base on it.

Galactica stumbles upon Kobol, the long-lost home world of humanity that the 13 Tribes came from, which legend says holds the only clues to the location of Earth. Roslin convinces Starbuck to steal the captured Cylon raider and return to Cylon-occupied Caprica with it to retrieve a religious artifact that will unlock the secrets on Kobol.

Infuriated that Roslin usurped his command by ordering Starbuck to steal the captured Raider, Adama decides that his only option is to storm Colonial One with marines and terminate her presidency. Starbuck reaches Caprica and finds the Arrow of Apollo in a museum, but she has to go through a copy of Number Six to get it.

Tigh's decision to impose martial law is protested in the fleet as well as on Galactica. On Caprica, Helo and Starbuck meet other humans.

Starbuck finds herself wounded in a hospital on Caprica where she is suspicious about her doctor. President Roslin makes an appeal to the fleet to follow her to Kobol.

Starbuck, Helo and Boomer bring back the Arrow of Apollo, but Boomer doesn't seem welcome. Commander Adama wants to keep the fleet divided and appoints a new CAG.

The Hybrid keeps jumping the basestar, and Roslin has visions. The three, D'Anna, is un-boxed. Humans and Cylons engage in a battle to destroy the Resurrection Hub. Baltar is badly wounded and Roslin has to decide whether or not to help him.
