Forced to take a precipitous route off the rimrocks and down into an unknown valley to escape certain death by four men pursuing him, Pete Knight, a cowhand seeking a job, sees a town ahead in the distance.

If he can just make it to that town, he believes he will be safe. Little does he know that he is heading into Gunsight, Wyoming, where a long-standing feud between the townsmen and the range men has reached the boiling point.

Arthur Hobart owner of the Diamond H has issued a warning that if the people of Gunsight do not stop victimizing his cowpunchers, he’s going to bring in his own law enforcer and burn the town down. And the appearance of Pete means only one thing to the townsfolk: Hobart is about to make good on his threat.

When Pete is jailed, he tries to convince Sheriff Mike Mulaney to get confirmation that he is not who the Gunsighters think he is. But before the matter can be resolved, Pete is lynched in the middle of the night by five men wearing burlap hoods.

When his Pete’s brother Ben, a US deputy marshal, arrives seeking vengeance for his brother’s hanging, he has even more reason to hate the town and what it represents than those on the Diamond H. But when Hobart tries to use Ben’s arrival for his own advantage, Ben must choose between protecting the town and abandoning his trail of vengeance or standing by while Hobart’s threats become reality.
