It's the dead of winter, a hungry wolf is out of food, and he's desperate.

Jasper is given an ultimatum by his master: break one more thing and you're out. Rodent Jerry does his best to make sure that his tormentor "gets the boot".

It's snowy and cold outside, and warm inside where Jerry squeezes past a mousetrap to cavort under a present-laden Christmas tree. Mistaking the sleeping Tom for a plush toy, Jerry wakes him and a mad chase ensues.

When a bulldog threatens Tom to keep away from his puppy, Jerry realizes that sticking close to the boy is the best way to keep away his feline tormentor. But Tom is not about to let the mouse evade him so easily.

Tom enters from stage left in white tie and tails, sits at the piano, gets his focus as the orchestra in the pit beneath him warms up, and begins to play Liszt's "Hungarian Rhapsody". Unbeknownst to Tom and the audience, Jerry is asleep across several of the high-note keys inside the instrument, so Tom's playing eventually wakes him. Jerry is pummeled by hammers, bounced by wires, and squeezed by Tom as the cat tries to play the concerto while dispensing with Jerry. Jerry's defensive antics add to the brio of the program and answer Tom with Jerry's own skillful musical attack. By the concerto's end, the duet leaves only one animal standing for the audience's applause.

Spike is guarding a private fishing hole - in his sleep. Tom sneaks in to do some fishing - with Jerry as bait. But one particularly vicious fish turns out to be more than Tom or Jerry bargained for, particularly when he wakes up Spike.

A lost baby woodpecker, that believes Jerry is its mother, does everything it can to save the mouse from Tom, who is once again in pursuit. A CinemaScope remake of the 1949 Tom and Jerry cartoon Hatch Up Your Troubles.

Tom, sick of Jerry stealing the milk out of his bowl, poisons it. Instead of killing the mouse, the potion transforms him into a muscular beast.

At the home of Viennese composer Johann Strauss lived Johann Mouse. Whenever the composer played his waltzes, the mouse would dance to the music, unable to control himself. One day, when Strauss was away, the house cat played his master's music. When word got out about a piano-playing cat and a dancing mouse, they were commanded to perform for the emperor.

Tom, whose appetite was whetted by a radio cooking program, wants to make a meal out of the pet goldfish. Jerry, who is friends with the fish, does what he can to thwart their feline foe.

A hungry cat has the idea of giving "Jumbo Gro" fertilizer to a scrawny canary to make him a bigger meal, which leads to a race between the cat, the canary, a dog, and a mouse to see who can grow the biggest.

Jerry takes a midnight snack from the fridge unaware that Tom is watching him.

Jerry is awakened from a nightmare by a knock on the door: someone has left a foundling in a walnut shell with a note, giving his name as Nibbles and saying he needs lots of milk. Fortunately, there's a dish handy, but it's next to Tom. Nibbles scurries out and dives off Tom's nose, then grabs a whisker for balance, waking Tom up. Jerry grabs him just in time and they hide under the milk. Tom laps up some milk and gets Nibbles; Jerry rescues him, and they run for the hole. Next, they try a very long straw; Tom catches them and sucks Nibbles through the straw. Much chasing follows, with a pause now and then for some milk. Tom traps Jerry in a milk bottle and chases Nibbles a while; he finally corners Nibbles and spanks him with a flyswatter. Jerry is so enraged he burst out of the milk bottle and lets out a ferocious roar; he grabs Tom by the tail and thoroughly pummels him, then stands over him as Tom feeds Nibbles milk.

When a duck hatches from the egg underneath Tom, the newborn (Little Quacker) is convinced Tom is his mother. Tom would like to eat the duckling; Jerry is determined to keep that from happening.

During yet another pursuit of Jerry, Tom ends up being killed when an upright piano slides down the stairs and slams into him. He meets a feline St. Peter at the gate of the Heavenly Express, but is initially turned away due to his constant torture. However, he will be allowed onto the train if he can have Jerry sign a letter of forgiveness within one hour. If not, it's Hell for Tom. Will he go up or down?

Tom is conducting a symphony at the Hollywood Bowl when Jerry comes out to co-conduct.

Tom steals an egg from a mother duck's nest, but soon the resultant hatchling runs away from the cat and into a mouse hole, where it finds an able protector in Jerry.

As Tom and Jerry stage their typical fight sequences, the patriotic soldier theme of the title is evidenced by such things as a carton of eggs labeled "Hen Grenades"; Jerry dropping light bulbs from an airplane like bombs; and Jerry sending a telegram with the message "Sighted Cat - Sank Same." Musical phrasings from various patriotic war songs are heard throughout.

Spike has just washed his pup. Tom and Jerry's chase knocks him into a mud puddle. Spike makes Tom clean him up again and promise to keep him clean which of course is Jerry's opening to get Tom in trouble.
