It makes a lot of difference who is the sheriff in the town of Lariat. When Grubb was sheriff, Kurt Dodd and his men ran wild. Cattle rustling was a business to them, and they went about it in a business-like fashion. Save for the valor and alertness of Bob Lee and his Texas men, they'd have wiped out the whole Tomlinson outfit.
When Bob Lee becomes sheriff, the war on the rustlers begins in earnest. Bob is elected to the tune of barking six-guns, and after his election the gunfire only increases, as Kurt Dodd's gang try to drop him dead.
In the fights for his life and for the safety of cattlemen, the only man Bob wants at his back is Dick Markley. Dick chooses a job that offers better money than sheriff's deputy, improving his chances to win the hand of one Miss June Tomlinson, leaving Bob to fight off Dodd's men without his help. Bob is faced with some difficult decisions: between love and friendship, friendship and his job, his life and his personal sense of justice; Bob will make choices that'll forever alter his destiny.
