Laramie booms with excitement when Lili Merrill, operator of the Birdcage Saloon, is appointed Chief of the volunteer fire department.

Marshal Dan Troop (John Russell) expects trouble when manager Jimmy Fresco (Walter Burke) brings his prize-fighter to Laramie. Samson (Mickey Simpson), an arrogant brute, beats all who enter the ring and expects to take over the town. When he makes a play for Lily Merrill (Peggie Castle), owner of The Birdcage cabaret and beats Deputy Johnny McKay (Peter Brown), Troop is convinced that he will have to meet Samson with bare fists.

Marshal Troop has to face an infamous gunman who arrives in Laramie with the announced intention of killing him.

Marshal Troop reluctantly makes Owny O'Reilly a deputy as a reward for fishing a dead outlaw out of a river. Owny, in turn, takes his new job too seriously and almost costs the marshal his life. 

Joe Knox (Edward Byrnes) quits a gang of cattle rustlers when they ruthlessly slay a young husband rushing for a doctor to save his ill wife.
