"Arizona Cowboy" Rex Allen heads the cast of Republic's Old Overland Trail. Rex plays an operative for the Bureau of Indian Affairs, assigned to pacify a disgruntled Apache tribe. Villain John Anchor (Roy Barcroft), a railroad contractor, has been stirring up trouble with the Indians as part of a complex scheme to build a spur line at slave-labor wages. Making things difficult for Rex is the fact that his wayward brother Jim (Gil Herman) has joined Anchor's gang. Of interest to audiences of the 1990s is the presence of Leonard Nimoy, here cast as Apache chief Black Hawk. Despite the surfeit of action in Old Overland Trail, Rex Allen finds time to sing three tunes.
