There are prisoners on board a transport ship are given a chance to earn their freedom. Water was just found, but the actual liquid contains too much salt. The ice that floats on top is pure water though. They just need man power to get the ice melted into liquid water that everyone can drink. Admiral Adama and Captain Lee Adama have turned to the prisoners for the manpower they need to melt this ice.
Once Captain Lee Adama and the others get to the ship, the prisoners rise up against the team and take them hostage. Tom Zarek is the leader of this uprising and demands for President Roslin to step down from office. He wants elections and for everyone to be free.
Also during this episode, Doctor Gaius Baltar asks Admiral Adama for nuclear weapons to help him determine who on board is a cylon. A chemical inside the weapon will detect the radiation that the cylon needs.
In the end, the hostages are let go and Captain Lee Adama is told that President Roslin has cancer. She doesn't know if she will be around for the election in seven months. Captain Lee Adama and his father, Admiral Adama, are butting heads about how to lead the colonies. This is getting worse, as Captain Lee has finally chosen a side, and not his father's.
