James Arness rides again as Matt Dillon, the U.S. Marshal he made popular in the 1955-75 television series. In this movie he goes after a renegade Apache named Wolf (Joe Lara) who has taken his daughter captive. As a bargaining chip, Dillon helps two sons of Apache chief Geronimo out of the fort stockade and offers them in trade. Dillon is aided by an Army scout, Chalk Brighton (Richard Kiley).
