Disgraced city cop Ray Tate and outcast state trooper Djuna Brown track down a wealthy sexual sadist and a depressed career criminal flooding a Midwestern U.S. city with killer ecstasy pills. Mismatched and mutually suspicious of each other, Tate and Brown hunt the mythic Captain Cook and his henchman, the homicidal Phil Harvey. But as Captain Cook sinks deeper into a spiral of sexual depravity, Phil Harvey begins to question his role as a lifelong gangster.
Tate and Brown discover, as they sift through the rubble left by their targets, that no one is what they appear to be not even themselves. Travelling through the Chinese underworld, clandestine drug laboratories, and biker-ridden badlands, the troubled duo encounter murder, political corruption, police paranoia, and psychosis, but can they find redemption?
