Bronco has been working as a mule-skinner for the Caleb White freight line at Fort Union but quits when they murder an Indian to steal his furs. Bronco is offered a job on the side-wheel steamship Mountain Queen on the Missouri River by its owner Martha Chandler. Bronco turns down the job. He has mixed feelings toward Martha and her son Rolf because Bronco, a deputy, killed her husband Frank during a bank robbery. Martha knows but Rolf doesn't and he is jealous of Bronco. When Bronco's friend Matt Crane, pilot on the Mountain Queen, is killed by White the gang, Bronco decides to take his place. The Mountain Queen can put White out of business. It has a load of Army rifles to take up river to Fort Benton. Rolf is overseeing the ship with Captain Taylor but Martha gives Bronco papers giving him control if needed. On board two unexpected passengers including the gorgeous blonde Gilda Harper and businessman Pollard have Bronco working to stay afloat.
