A moment after a bottle of white shoe polish pours on Jerry, Tom hears on the radio that a white mouse, having swallowed an explosive, has escaped from an experimental laboratory and that slightest jar of the mouse could cause it to explode and blow up the entire city. It is then that Tom notices now-white Jerry and concludes it's the escapee.
Spike is building his dream house when Tom crashes into it mid-chase. Of course, Jerry then takes every opportunity to route the chases through the construction project.
Tom is the official cat on the cruise ship S.S. Aloha, but he'll be kicked off if the captain finds even one mouse. That one, of course, is Jerry, who sneaks on board just before sailing.
Tom's being especially lazy, which makes it even easier for Mammy to toss him out when her new mouse-catching robot cat, Mechano, arrives. Mechano is frighteningly efficient, foiling several attempts by Jerry. Jerry turns this efficiency against him by unleashing several mechanical mice; the zealous robot makes a shambles of the house, and finally itself, in the process of chasing them down. Tom is welcomed back, but at the last moment, a key part of the robot had gone down Tom's throat; Jerry activates it, and sends Tom chasing after one of the wind-up mice.
Jerry removes a tack from Spike's paw. In gratitude, Spike gives Jerry a bell to ring when he's in trouble.
A baby seal escapes from the circus and ends up in Jerry's backyard pool. Tom finds out soon enough, and when the circus offers a $10,000 reward, his goal is clear.
Someone drops off three cute little kittens; Tom is put in charge of them while Mammy goes shopping. But behind her back, the three little angels are real devils.
Tom's in love again, and Jerry's devil conscience reminds him of times this has happened in the past (which, of course, we see, in the form of clips from earlier shorts), and how that's been nothing but trouble for Jerry.
Tom, a castle soldier in 16th century France, is assigned to guard the food laid out on a banquet table. Jerry and a smaller mouse companion, two wandering "mouseketeers", make the situation miserable for Tom as they abscond with (and occasionally eat) all the food they can.
Tom is duck hunting, and he wings a little duckling that can't quite keep up with the flock. Jerry gets to the fallen duck before Tom, bandages his wing, and shelters him from Tom as he keeps running out to join his flock.
Two sisters reunite after not having seen each other for five years. While catching up on each others' lives, they relive childhood experiences, both good and bad.
