 Ex-prize fighter Mark Miller (Stanley Clements), now a sports writer, sets out to expose a murderous gambling ring led by Dano Rizzo (Red de Corsia.) He first learns about the ring when when a fighter dies as a result of ring injuries in a mis-matched fight. The boxer took the fight because of his love for Doris Burton (Veda Ann Bord), actually the girl friend of Rizzo. Doris  brother Bill (Scotty Beckett)gets involved when Rizzo threatens to ruin the (questionable)good name of his sister, unless he helps the gang with some fixed bets. The always welcome and lovely Gloria Henry (as Kerry Barker) is on hand as Miller s girl friend.
