Houston cop Jack Caine (Dolph Lundgren, Rocky IV, Masters of the Universe) is a not-by-the books police officer investigating the death of several people, including his partner, by a gang called the "White Boys." All the victims seemed to have died of drug overdoses, but Jack thinks that there is something more sinister afoot. His investigation reveals a plot by aliens who use the bodies to extract a chemical that is sold to addicts on their home planet.
