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. Saving the Emperor — and the Empire — appears to be a lost cause, unless Vader can uncover the secrets of the Jedi Council and locate the mysterious Ghost Prison. 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!
