James Arness rides again as Matt Dillon, the US Marshal he made popular in the 1955-75 TV 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 (Kiley). Written by John Sacksteder
