Detective Dan McKenna (Lorenzo Lamas) is a big-city cop with a take-no-prisoners attitude and a taste for payback. When he's not out to exact revenge on the slime who murdered his wife, he's infiltrating the Russian Mafia to prevent a breach of national security. In a striking move to gain both revenge and justice, McKenna undergoes plastic surgery to assume the identity of Lyle Mason, a criminal who shot McKenna in the face. Posing as Mason, McKenna seeks out Frank Dallio (Conrad Dunn), who murdered McKenna's wife and holds a valuable microchip.
