Battlestar Galactica (2003) - TV Movie: Razor (2)

Shortly after Lee Adama is put in command of the battlestar Pegasus, he brings in Kendra Shaw as his XO. Shaw began serving under Admiral Cain just as the Cylons attacked the 12 Colonies, witnessing first-hand the choices Cain made that kept Pegasus and its crew alive, experiences that helped mold Shaw into a razor.

When Lee is ordered by his father to rescue a missing scientific crew, they discover a missing link to the Cylons' past experiments on humans during the Cylon War, which may in turn be a key to everyone's future.
