A traitorous uprising against the fledgling Galactic Empire leaves Emperor Palpatine close to death. The only ones standing between the insurgents and victory are Darth Vader, the cybernetic Moff Trachta, and a crippled young Lieutenant fresh from the Academy.

The odds are stacked against them, and the future looks bleak. But that's exactly when the power of the dark side is the strongest!
