Harried paleontologist David Huxley (Cary Grant) has to make a good impression on society matron Mrs. Random (May Robson), who is considering donating one million dollars to his museum. On the day before his wedding, Huxley meets Mrs. Random's high-spirited young niece, Susan Vance (Katharine Hepburn), a madcap adventuress who immediately falls for the straitlaced scientist. The ever-growing chaos -- including a missing dinosaur bone and a pet leopard -- threatens to swallow him whole.

Medfield's lovable but hopelessly absent-minded professor, Ned Brainard (Fred MacMurray), bounces back in this classic Disney film with hilarious new mishaps when he experiments with the amazing by-products of his startling anti-gravity substance, "flubber." Windows shatter, football players fly and thunderstorm materialize indoors as Professor Brainard fights to keep Medfield College from falling into the hands of ruthless land developer Alonzo hawk (Keenan Wynn).

Claude Rains may have meddled in things that Man must leave alone, but that doesn't mean Woman shouldn't get in on the act. Kitty Carroll (Virginia Bruce) answers an ad in the paper to be an experimental subject for John Barrymore's dauntingly daffy Professor Gibbs, whose invisibility serum, if successful, promises to replenish the dwindling fortune of his benefactor, Dick Russell (John Howard) - if only he can get a human subject. Kitty's aim, however, is to wreak havoc on the draconian boss of her modelling job, the aptly named Mr Growley (Charles Lane).
