A customs bust in New York alerts Mack Bolan to a heroin smuggling operation run by Russian gangsters. His mission is three pronged: find the brain behind the enterprise, smash the network that stretches from New York to Moscow and protect the beautiful Russian witness from enforcers working around the clock to kill her. RULES OF ENGAGEMENT Undercover — as a rogue cop on the take — Bolan penetrates the drug ring and finds tentacles reaching deep into the U.S. justice system. Shooting his way out of a blood bath at every turn, the Executioner winds his way through the maze of corruption and death, delivering the kind of payback these criminals have coming to them.
