Lamas has dual roles as Det Dan McKenna and Russian Mafia liaison Lyle Mason. An FBI surveillance gone wrong gets McKenna's wife killed but not before she takes Mason with her. FBI agent( Billy Dee Williams) notices that Mason and McKenna look alike and with a little help from plastic surgery McKenna becomes Mason. Pain killers that seem to have the side effect of causing McKenna to become violent help to keep the charade going. The violence is never ending - the story line takes a back seat - and Lamas shows off all the right martial art moves.The ending looked like they were hoping for a sequel but it never happened.
