Battlestar Galactica: Razor (2007)

Synopsis
The untold story of the Battlestar Pegasus comes to the screen in this special, two-hour episode of Battlestar Galactica detailing the transformation of Major Kendra Shaw into a fearless tool of war known as a "razor." As the Cylons prepare to launch a genocidal attack on the Twelve Colonies, Major Kendra Shaw (Stephanie Chaves-Jacobson) arrives on the Battleship Pegasus reporting for duty. In the aftermath of the devastating attack, Major Shaw is trained by Admiral Helena Cain to employ suicidal fighting tactics and commit atrocious war crimes against her own people. Any sense of hesitation or doubt is methodically stripped away from Major Shaw, rendering her a living weapon driven by murderous instinct. But such a weapon can ultimately do as much damage as it does good, and it isn't long before this severe form of warfare takes a heavy psychological tool on the tormented Major Shaw. ~ Jason Buchanan, All Movie Guide
