Cheyenne #11

Bronco Layne goes to the town of Trinity to help his friend Jim O'Neil who is about to be hanged for the murder of Colly Smith. Layne investigates Duke Rhein, a cattle owner, and finds out that he and his thugs are smuggling opium across O'Neil's ford in the Rio Grande river by packing it inside hollowed out cattle horns. Duke had also killed the ranger who knew too much and framed O'Neil. Bronco tries to stop O'Neil's execution but finds out that Jim's wife and daughter are held hostage. When he finally finds them, O'Neil can then say what he knows and the guilty are brought to justice.
