Is There a Doctor in the Mouse?

The Bide A Wee Mouse Home has sent the orphan mouse Nibbles to spend Thanksgiving with Jerry. Unfortunately, Nibbles is always hungry.

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.

Professor Jerry teaches a course in how to outwit cats, but his pupil seems to know more than Jerry.

The couple that owns Tom and Spike decides they can't afford to keep both. They agree that the first one to catch the mouse can stay - bad news for Jerry.

Jerry's eccentric uncle, Pecos, a Texan mouse, comes to spend the night with him before his musical performance on television the next day. He decides to rehearse with his guitar for the performance but each time he plays, one of his guitar strings snaps off. Fortunately, he is able to replace them by plucking off one of Tom's whiskers each time. Tom is rather reluctant about this and tries to hide to protect his whiskers from Uncle Pecos.

Mammy steps out for the evening. While she's away, the cats - in this case Tom and three of his alley cat friends - play. Play and perform rollicking jazz, that is.

Jerry and his little French mouse friend are raiding while the king sleeps. They awaken him and he calls for Tom to give him an ultimatum: One more sound from the mice and it's off with Tom's head. The mice hear this and team up to torment Tom.

It's Independence Day, and Jerry's little nephew, Nibbles, wants to celebrate with fireworks, while Jerry reminds him to "keep it safe and sane."

Tom pretends to have a cold in order to trick Mammy into letting him stay inside for the night. Jerry tricks Tom by making him think he really is sick - with the measles.

Spike is taking his son on a picnic. Jerry keeps hiding in the basket, so Tom keeps disrupting the picnic while chasing him.

Jerry rescues a bag of puppies from the river. Most of them run away as soon as Jerry releases them, but one stays behind. Jerry tries to get rid of it, but ultimately takes pity and invites the frisky pup inside, where he has to hide it from Tom, who keeps throwing it out.

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.

Tom and Jerry are in a cabin in the wild west. Jerry's rustling food, so Tom's owner won't let him eat until he's gotten rid of Jerry.

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?
