In "Terror of the Plains," Tom Tyler is the cowpoke who learns the blackhat who framed his pappy for murder is hiding out in a ghost town where other ornery fellows congregate. In order to get to the nasty criminal, Tom masquerades as a bandit while his sidekick poses as a sheriff who's after him. Roberta Gale, William Gould co-star. "Tracy Rides" is the exemplary Tyler western yarn with Tom as a sheriff whose girlfriend's brother is involved with a gang that raids an elderly sheepherder's ranch, then kills him. Tom's terrific, but he's stuck between his loyalty to his job and his girlfriend and her family. With Edmund Cobb, Virginia Faire. 115 min. total. Standard; Soundtrack: English.
