Mission: Impossible (1966) : 3x3

Jim manages to avoid Whelan by hiding in the tunnel pipes overhead. He gets access to a list of Whelan's bookies. Meanwhile, Barney-as-Richy fights his way through a series of matches, helped by a concealed gas emitter in the ring beneath his opponents' corner. Finally Barney faces Buckman's champ Staczek, with orders to take a dive. He knocks out Staczek against Buckman's orders, leaving Buckman to be bankrupted covering the bets.
