Tom Rynning learns that Bart Evans' will includes a clause that requires Betty Evans to give $10,000 to the man the rancher hired to killer the Ranger captain - and his daughter is willing to pay the bounty.

Captain Rynning and several of his Rangers join a posse to smoke out the remnants of Luke Baxter's gang. The outlaws momentarily give the posse the slip and double back to take refuge in a mission school run for the reservation's Indian children and hold the priests and the youngsters as hostages.

When an Apache inadvertently kills an elderly chief, the Rangers set out to defend him against his Apache accusers.

The territorial governor orders Rhynning to clean up prize fighting in Arizona. The Ranger captain focuses his attention on Barker, a promoter who offer $500 to anyone who can stay in the ring for four rounds with his champion. The problem is that, while suckers throw their money away betting on the challenger, there's nothing illegal about the promoter's activities.

Rynning orders Frank Seldom to meet a stagecoach heading from New Mexico to Wilcox, Arizona to ensure its cargo of six lovely mail-order brides arrive unscathed. Seldom has his hands full fending off marauding Apache Indians, crooked stagecoach drivers and an outlaw gang who intends to kidnap the women and sell them to white slavers in Mexico.
