Luke Walsh makes the biggest mistake of his young life: he falls for the beautiful Dee Dee Bright and she tricks him into killing the town marshal of Tuscon, Arizona. There is nothing for it but to take to the desert. But when his pony founders he finds himself afoot and alone on the long land. Saved from death by some passing men, he is taken to a lonely outpost in the hills and set to work doing slave labour in a gold mine. Worse, Luke soon discovers that the place is an outlaw sanctuary. When Dee Dee Bright shows up again, it is on the arm of her boyfriend, the gunman Virgil Sly. As more armed men arrive, Luke is left with two choices: to try and escape the outlaws and their killing guns, or return to the desert where his pursuers await him with a hanging noose.
