A nine-year-old Elizabeth Taylor made her film debut in this lively comedy. She plays the spoiled-brat daughter of a pudding manufacturer who has been entered into the town's mayoral race by some of the local businessmen. They have chosen him because they think he is easy to manipulate. As a sales gimmick, the pudding magnate advertises that his product contains the highly nutritious "Vitamin Z." He suddenly begins selling pudding like crazy and soon his political campaign is well-funded. Unfortunately, there is no "Vitamin Z" and when this is discovered, the town fathers try to dump him and show that he is a fake.

West of Carson City remains one of the best of Johnny Mack Brown's Universal westerns. The story takes place in a gold-rush community where the locals are taken to the cleaners by duplicitious Eastern gamblers. When it becomes obvious that the local constabulary has been "bought off" by the crooks, two-fisted cattleman Jim Bannister (Brown) swings into action. The film's highlight is an outsized fistic brawl between the hero and secondary villain Breed, played by loose-limbed comic stuntman Frank Mitchell.

A down-on-his luck businessman organizes an excursion to Sir Henry Morgan's Island for a treasure hunt only to encounter a mysterious phantom and murder.

During a test, a race car using an experimental oil fueled engine blows up, killing the driver. Lucky Taylor, a stunt driver, is initially blamed for the accident, but is later cleared. He thinks the engine design has a real chance to win races, but the racing association has banned it since the accident. He devises a scheme to have a car equipped with the engine entered into a race, without race officials-- or the engine designer's sassy daughter -- finding out about it.
