Hayden Christensen and Nicolas Cage star in this medieval action adventure. Set in the Far East, the story follows the British crusader Jacob (Christensen) as he tries to protect a young Chinese prince and his sister from the assassination attempts of their older, power-hungry brother Shing (Andy On), who wants the imperial throne for himself. But struggling with an opium addiction and haunted by his past battles, Jacob must rely on the support of his former mentor Gallain (Cage), who is now living as an outlaw known as the White Ghost, to defeat Shing's forces.
