Keeping Mum

Even though Mickey's evening started slow and lazy, things get moving in a hurry when Minnie calls from outside the big dance, wondering why he's late. Luckily his best pal Pluto is happy to help wrangle the uncooperative evening wear and help get him out the door...without the tickets

Tom is shipwrecked on an island, which is inhabited by at least one mouse - Jerry. To thwart the hungry cat, Jerry disguises himself as a cannibal.

Tom heads for a big city penthouse to become acquainted with a rich pretty female cat that lives there. He brings her Jerry as a gift and does some humiliating things to Jerry. Jerry, in turn, attracts the attention of another cat who also becomes interested in the female cat. It eventually turns into a fight between Tom and the other cat for the lady's hand but Jerry is the one who gets her in the end.

Spike the bulldog, grateful to Jerry for getting him out of the dogcatcher's van, offers to help the little mouse any time he whistles. Tom, Jerry's feline tormentor, seeks to overcome this new disadvantage.

Mickey is preparing to conduct an opera when he chases Pluto away. Pluto crashes into a magician's props backstage and spars with the hat, its rabbits, and its doves. The opera begins: Clarabelle plays flute, Clara and Donald are the leads in Romeo and Juliet. Pluto follows the magic hat onstage, to Mickey's growing annoyance. The hat falls into a tuba, and soon the animals are filling the stage.
