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.
