Tom gives Jerry, as a present to a girl cat he really likes. The girl doesn't accept the gift, and Tom goes back to the house with a pout. He hears on the radio about a zoot suit. Tom cuts out and sews together a very tight and nice-looking suit. He goes back to the girl cat's house, and as soon as she sees Tom's new suave look, she swoons. Tom acts like Charles Boyer, and he makes the girl fall in love with him. Jerry sees he has to ruin this. He does something to anger Tom, which makes him chase Jerry around the house, and tripped into a fishbowl. The suit shrinks to Jerry's size, and Jerry wears it. He takes Tom's place, and acts like a mini Charles Boyer to the girl cat.
