Elmer attempts to elope with his fiancée, but they escape her parents by driving off in a car that's actually owned by a wanted gangster. When they hear on the radio that the police are looking for them, they dump the car and hide out near a farmhouse. But the farmer's radio also broadcasts the couple's description, so they run away and start hitchhiking, only to be picked up by two policemen. They manage to flee into a railroad yard and hop a train that turns out to be refrigerated. Finally they decide to turn themselves in -- just as they learn that the real crooks have been apprehended.

Elmer owns a gas station out in the California desert. Soon he has a business rival in Jim, who opens up another station, and is also trying to steal Elmer's girlfriend. She plays both rivals against the other and, because she is a baseball fan, both Elmer and Jim try to show each other up in the big local baseball game.

A hillbilly family, hard-hit by the end of Prohibition, decide to set the biggest brother up as a professional wrestler.

Buster becomes a fireman, but unfortunately not a particularly good one. He has a chance to prove himself, however, when three women are trapped in a burning building.

The just-out-of-college, effete son of a no-nonsense steamboat captain comes to visit his father whom he's not seen since he was a child.

Conrad Nagel, representing the Hollywood movie community, and Jack Benny, representing the Broadway stage community, act as the interlocutors of a musical comedy revue. A plethora of chorus boys and girls are featured front and center in some of the song and dance numbers, and provide back-up to some other acts. But the revue primarily is a vehicle to highlight a cavalcade of Hollywood movie and Broadway stage stars. One early running gag has both Nagel and Benny playing straight man to Cliff Edwards, who just wants a nice introduction to his act. Edwards would return later to be featured along with the Brox Sisters in one of the highlights of the second act, a production number around the song "Singin' in Rain", complete with rain soaked stage. A reprise of the song with the entire cast acts as the revue's finale.

When Prohibition ends, a barber tries to get in the liquor business only to come up against mobsters.

A Scoutmaster falls for a beautiful young carhop, but finds that a beefy traffic cop is also courting her--and he doesn't want any competition.

Jeff wants to get married to Virginia, but Virginia won't marry until her older, hard-to-please sister Angelica gets married off first. Jeff pretends that a shy, never-married nobody he has just met is really a great lover, in order to get Angelica interested in him.

Elmer Tuttle, a plumber in Paris, is enlisted by beautiful Patricia Alden to help her make her lover Tony Lagorce jealous. Tony, however, is two-timing Patricia with Nina Estrados. Elmer, with the help of his friend Julius, hopes to use the high-society contacts he's made with Patricia to find a market for his new invention, a pistol with a range-finding light. But Elmer's attempts to interest a military leader are mistaken for assassination attempts, and with Tony and half the male uppercrust of France challenging Elmer to duels, he is in hot water not even his plumbing skills can drain away.
