It started out as a drunken prank ... but when one man died and his fellow passengers aboard the Tucson-Tombstone stage were involved in a devastating crash, it was no laughing matter. Wells Fargo's top troubleshooter, Clay Nash, was dispatched to find the cowboys responsible, and uncovered a criminal enterprise that might otherwise have gone undetected. Those drunken pranksters were actually tough as nails and handy with their guns, and they were ready to fight him all the way to avoid paying for their crime.But Clay had an ally as he rode the slaughter trail ... a beautiful Mexican girl who wouldn't stop until she had her revenge on the men who'd killed her father!
