High Explosive

Mike Douglas (Barry Sullivan), owner of a nitroglycerin concern hires his old friend Buzz Mitchell (Chester Morris), a race-driver of midget-auto cars who has been banned from racing, to go to work hauling nitro. Buzz makes a play for Connie Baker (Jean Parker), Mike's secretary and girlfriend, and also for Doris Lynch (Barbara Lynn), fiancée of Connie's younger brother, Jimmy ('Rand Brooks'), and gets Jimmy to replace him on a dangerous nitro haul and Jimmy, of course, has an accident and gets killed. But Buzz finds a way to redeem himself. The hard way.
