Having just jumped away from a battle with Cylons and rejoined the civilian fleet, a Cylon virus forces Galactica to switch to a limited emergency power as the crew fights off a boarding party of Cylon Centurions.

With Galactica safe, Doctor Cottle makes his way to operate on a still-critical Commander Adama.
