The episode begins with Tom chasing after Jerry as usual, but their pursuit comes to a halt when they come across a strange-looking laboratory. The two curious animals take a peek inside the window, only to find a scientist working on a new potion.

The scientist, Dr. Jekyll, is trying to create a new formula that will make him young and handsome again. However, he is struggling to find the right ingredients and has failed multiple times. Tom and Jerry watch from outside as Dr. Jekyll accidentally spills a potion on himself and transforms into a handsome and friendly version of himself, named Mr. Mouse.

Tom manages to get hold of the potion and drinks it himself, hoping to catch Jerry and Mr. Mouse easily. However, instead of turning into a handsome version of himself, Tom transforms into a monstrous cat that chases after the frightened animals.

The episode comes to a climax when Dr. Jekyll, now turned into Mr. Mouse, tries to stop Tom's rampaging. Jerry and Mr. Mouse team up to escape, while Tom's monstrous form causes chaos all around them. The animals eventually find themselves back in the laboratory, where Dr. Jekyll's assistant pours the antidote into Tom's mouth, ultimately turning him back to his regular self.

In the end, Dr. Jekyll realizes that the potion's power is not worth the consequences and decides to stop his experiment. Jerry and Tom are back at their usual chases, but with a new friend in Mr. Mouse, who occasionally rides to their rescue.

Overall, "Dr. Jekyll And Mr. Mouse" is a fun and entertaining episode that adds a touch of science fiction to the classic cat-and-mouse chase. With a twist on a classic story, the episode shows the importance of accepting oneself and that some experiments are better left alone.
