An alley cat is foraging for food when he sees Tom's house and decides it's a rich haul. He dresses as a foundling baby and lands on the doorstep. Tom takes him in and Butch proceeds to raid the fridge between Tom's babying him. What he doesn't know is that Jerry's going to grab the ham Butch swiped every chance he gets.
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.
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's chasing Jerry when he runs right into a sleeping dog and the two of them must work together to fend him off.
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.
Jerry runs into a dog pound (and right on top of a napping Spike) to escape a rather mangy-looking Tom. To avoid being ripped to shreds, Tom borrows the head of a nearby dog statue. This easily fools the dogs, but not Jerry, and Tom keeps losing his newfound head...
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.
Tom ties up Spike and sneaks into the courtyard of the glamorous Toodles Galore with his bass, hoping to woo her with his song, much to the annoyance of a sleeping Jerry.
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.
Jerry crashes a vase onto Tom's head, which gets Mammy to throw Tom out. Jerry at first revels in his freedom, but soon tires of this, and, under a flag of truce, hatches a plan with Tom.
Tom's new book on "how to catch a mouse" doesn't prove too helpful against Jerry; actually, Jerry seems to make better use of it than Tom.
Tom is playing with Jerry when a cute lady cat is delivered to Mammy for her to take care of. Tom is smitten at first sight.

It's spring, and Tom is much more interested in the female cat next door than in Jerry.
