The Stooges, proprietors of a local drug store facing lease expiration due to the obstinate landlord Amos Flint, witness his maltreatment of his elderly wife Cerina.

However, a mishap involving bubble gum instead of marshmallows adds a comedic twist to their celebration.

When Amos encounters Cerina's rejuvenated state, he reconsiders his eviction threat but inadvertently transforms into a gorilla after overdosing on the elixir.

Subdued by the Stooges, Amos is confined, prompting the trio to entertain the idea of exhibiting him as a talking gorilla.
