It's springtime and love is in the air particularly for Mr. Magoo. Magoo is disappointed to learn his nephew, Waldo, had a fight with his girlfriend, Juliette. Magoo plans to have Waldo and Juliette reunited but instead of going to Juliette's apartment, he goes instead to a boxing ring where a boxing female kangaroo is sparring. Magoo mistakes the kangaroo for Juliette and invites her home to meet Waldo. Unfortunately, the kangaroo is trained to throw punches every time she hears a bell and Waldo is usually at the receiving end of the blows.
