An American shipload of Caplock rifles has been unloaded on the Texas coast. This new-fangled firepower could be vital to the Texians fighting for freedom from Mexico ... if it ever reaches its destination. There's only one man General Sam Houston trusts to escort the Caplock shipment, and that's Jackson Baines Hardin ... the 'Ole Devil' himself. Ole Devil is a man to be reckoned with, and this time he's got a pistol-packin' girl and a sword-swinging Oriental in his corner. But he hadn't counted on the ornery likes of a vicious Mexican general ... or a townful of cutthroats lusting after the rifles for loot ... or a vengeful woman whose renegade gang would stop at nothing to stop Ole Devil!
