On the ground, things are heating up. Tyrol (Aaron Douglas) leads a rescue team to save Cally (Nicki Clyne), Laura Roslin (Mary McDonnell) and others from summary execution. Meanwhile, Sharon (Grace Park) must fight her way out of an ambush set up by the Cylons, who have been tipped off about her arrival. Humans and Cylons alike face agonizing choices. Tigh (Michael Hogan) learns that Ellen (Kate Vernon) has been feeding information to the Cylons. Kara (Katee Sackhoff) must wrestle with her love for Kacey (Madeline Park), her half-Cylon child. And the Cylons grimly ponder their options as they lose control over the humans on New Caprica, ? the final solution may be to put an end to this misguided experiment in peaceful co-existence by nuking the colony. Adama?s rescue effort becomes a desperate race against the clock. Sharon infiltrates the Cylon detention center and recovers the launch keys to the human ships. When Adama gets word of her success, he orders Galactica to Jump to New Caprica and engage the Cylon fleet.
