Double Agent Stallion

A Russian master spy, nicknamed the Fisherman, dispatches a sultry young redhead to an American college campus to ensnare a promising student into a compromising position where he'd be forced to spy for Moscow. Early on, he becomes suspicious and goes to the FBI which persuades him to become a double agent. Years later, after he's "proven" himself to his handlers with carefully vetted intelligence, he provides some clever technical misinformation designed to sabotage one of their major weapons programs. To protect their high value asset from retribution, the FBI stages the family's "death" in a flaming car accident. When inevitably the Russians realize they've been snookered, the Fisherman sends two experienced killers to check out the car accident and hunt him down, if he's alive and in hiding. He and his family are in the witness protection program, with new names and appearances, but the determined killers manage to track them down anyway. A gunfight ensues.
