Bud watches a Western movie on television and shrinks himself down to the size of a bug to visit a Western bug town that he built around his electric model railway. He becomes the sheriff of the town and even falls in love with a singing earwig named Ramona.
Un jour d'ennui, Bud se miniaturise et crée une ville western miniature peuplée d'insectes cow-boys minuscules. Alors qu'il ne faisait ça que pour s'amuser, il va tomber amoureux d'une chenille chanteuse de cabaret.
