In previous volumes, Arty Anderson, a teenage cowboy, has survived scrapes with a cougar and a flash flood, but this time he's up against a classic western villain--cattle rustlers! Long-time enemy, Jeff Chastain, is back with a gang of outlaws who have escaped from prison. When they learn that a posse is organizing to come after them, Chastain plans a diversion that could spell disaster for the Circle A ranch. Ride along as Arty, Marshal Bodie and the ranch hands get help from Little Hawk, the Indian boy who lives at the ranch, as they chase down the bad guys and have a showdown before they can reach Mexico.
