"Brothers of the West" is one of a bazillion B-westerns that were made in the 1930s. However, among these, it's certainly one of the lesser films as it's made by a lower than usual budgeted small studio and the quality is correspondingly low. Plus, to be quite blunt, Tom Tyler has the personality of a bag of lint compared to most other cowboy stars.
The film begins with Tome Wade (Tyler) about to go on vacation when he learns that his brother is wanted to murder in some western town. He knows his brother and knows it's all a mistake, so using his detective skills, he decides to investigate. However, he doesn't divulge to anyone in the town that he's a professional investigator.
When he arrives in town, he learns that his brother still hasn't been caught--and he assumes he is either dead or being held captive. He also soon meets Miss Chandler, the nosy and stupid daughter of the murder victim. When folks start taking shots at him, Wade realizes that something bigger is going on in this crappy town.
Like the lowest budgeted westerns, this one lacks incidental music, a sidekick and the great stunts and flourishes the better B-westerns usually had. It's not a terrible movie (though some of the acting sure is) but is one only the most die-hard fans of the genre will enjoy.
