Joel Shelby and his friend Tex travel to a friend's wedding, and on their journey back home, they learn that the man whom they had captured a year ago had escaped from the jailhouse in Tuscon with the help of a gang of outlaws, leaving a few people dead and wounded in the town as they left. Joel organizes a posse with Tex and a few other men, and they trail the outlaws into New Mexico territory. After a few escapades, the posse track down the outlaws near Santa Fe, but with the civil war raging nearby, capturing them isn't going to be easy.
