The film centers on a trio of bumbling pest exterminators: Moe Howard as Moe, Larry Fine as Larry, and Curly Howard as Curly, who find themselves short on clients and decide to pull a risky scheme. They stage both the infestation and the response, hoping to drum up business by creating chaos and then presenting themselves as saviors. Their plan hinges on sneaking into a glamorous mansion under the pretense of solving a grand problem, all while they themselves spark the very nuisance they promise to eradicate.
Inside the affluent house, the night unfolds around a high-society dinner party, and the trio moves with the casual confidence of guests rather than workers. The hostess Mrs. Beulah Burlap, played by Clara Kimball Young, hosts the elegant affair, where appearances must stay flawless even as trouble brews in the lamps and corners. The Stooges’ scheme begins to take shape as they discreetly scatter various vermin—mice, moths, and ants—throughout drawing rooms and a chandeliers-lit hall, all while maintaining a veneer of ordinary party-goers. Their improvised antics weave through the dinner, and what started as a ruse to attract business gradually earns them an odd kind of employment: they’re hired to fix the chaos they created, slipping back into the role of amateur professionals while still masquerading as guests so as not to ruin the evening’s refinements.
The plan, however, spirals into a showcase of slapstick misfortune when a carefully hidden element goes awry during a recital of Johann Strauss II’s Blue Danube Waltz. A sequence involving cats secreted inside an upright piano provokes a whirling cascade of chaos—the piano becomes a stage for pandemonium as the felines scramble and the moment descends into a loud, tangled frenzy. The Stooges’ frantic attempts to salvage the situation only heighten the uproar, and the instrument itself ends up damaged in the process. Yet the social order of the party endures, with the hostess and the guests interpreting the uproar as a source of entertainment rather than embarrassment, allowing the night to proceed with an air of festive absurdity rather than crisis.
As the merriment crests, the trio is invited to one more flourish: a fox hunt for added amusement. The misadventures reach a final, farcical peak when Curly—always a wildcard in their schemes—stumbles into another bout of mayhem during the hunt. A skunk is mistaken for a fox and pulled from a sack, then brandished in front of bystanders, triggering a wave of smelly consequences that leave everyone—horse, riders, and onlookers—reeling in the aftermath. The skunk’s odor sweeps through the scene, capping the night with a quintessentially punishing note of slapstick humor that underscores the Stooge’s persistent streak of ill-fated meddling.
Throughout, the film maintains a breezy, light-hearted tempo, balancing deft physical humor with the charm of a bygone party atmosphere. The trio’s misdeeds are always tethered to a sense of playful mischief rather than malice, and the crowd’s willingness to embrace the chaos helps keep the mood buoyant rather than ruinous. In the end, what began as a double-edged plan to chase business spirals into a showcase of resilience—the hosts, guests, and the improvised entertainers finding a way to turn every blunder into shared amusement.
