Jimmy joins Cannonball on a visit to the widow Fennamore, Cannonball's old girlfriend, at Firehole. Engineer Colton is killed by henchman Smoky Morgan and Philip Judson hides the body. The engineer, at the request of the widow's niece, Martha, had come to inspect a polluted reservoir. Land Company head Turner and Judson contaminated the water to get the ranchers to vacate so they can grab the land. Judson hires Easy to pose as the engineer, and he reports the reservoir useless but Jimmy's test proves the waters are not deeply polluted. Judson kills Easy to keep him from talking, and casts the blame on Cannonball. But Jimmy has a trick up his sleeve, right after the next song.

In this western, two cowboys are framed as cattle rustlers and tossed in the pokey. Later, honest ranchers spring them and together they ride out against the rustlers.

Despite his unprepossessing screen personality, singing cowboy Jimmy Wakely was starred in a series of Monogram westerns, one of which was West of the Alamo. Wakely and comedy sidekick Lee "Lasses" White play a pair of government agents who work undercover to solve a series of baffling crimes. It comes to no one's surprise that the criminal mastermind is the town's leading citizen, in this case banker Clay Bradford (Jack Ingram). As was typical in the Wakely westerns, West of the Alamo is approximately 25 percent action and 75 percent musical. Among the guest warblers this time out is the Arthur Smith Trio, headed by a gospel singer who'd later emcee a popular religious TV talk show.

Jimmy Wakely and his sidekick "Lasses" White run into trouble as they attempt to hire some cattle cars on the Cattleman's Railroad to take their herd to market. Rancher Joseph Colton has bought up all the cattle cars and intends to purchase the penniless line from principal stockholder Gywnn Randall. She is eager to sell to Colton but doesn't realize that he intends to force all the ranchers out of business once he has control of the line.

Jimmy Wakely and Dusty, traveling with the medicine show owned by "Lasses" White, stop at the Ferguson ranch and find the rancher and his wife killed. They take the Ferguson baby to their camp, where outlaws Joe, Slick and Pete attempt to kidnap the baby, while Dusty is reporting the murders to Sheriff Beasley and town mayor Melinda Pringle. Wakely and his singers hide the baby from its legal guardian, Doc Judd Thomas, as they suspect him of being connected with the Ferguson murders.

In the gay '90s, cardsharps take over a Mississippi riverboat from a kindly captain. Their first act is to change the showboat into a floating gambling house. A ham actor and his bumbling sidekick try to devise a way to help the captain regain ownership of the vessel.

A musical short.
