English prize fighter Gentleman Jim Dawson comes to the goldfields with two friends, Symons and Green, supposedly to pan for gold. Instead, they intend to cheat the miners by getting them to bet on Gentleman Jim when a fight is staged - and rigged - with one of the local toughs, Peter Hackett. The miner's anger is aroused when Comm. Fitzalan orders that the fight be held in a closed tent with only himself and selected guests present. Sgt. McKellar has to act swiftly in order to prevent a riot, and the ensuing action provides an opportunity for a wandering priest, in whose care the bets have been entrusted, to sneak away with the money.
