Sylvester Stallone stars as a cop named Marion Cobretti -- Cobra for short -- in this action-thriller whose mile-a-minute pacing, dash of humor, and impressive stunts will entertain the most demanding fans. His partner is Gonzales (Reni Santoni) and both work for a special unit that is called in when ordinary methods fail. Cobra and Gonzales are assigned to track down a serial killer and at the same time protect Ingrid (Brigitte Nielsen), who seems a likely bet to become victim number 17. The action heats up when they discover that the "one" serial killer is really a whole gang of neo-Nazi locos.
