Ed Walters, an auto mechanic, falls for the intelligent and beautiful Catherine Boyd. It is love at first sight. There is however a problem: she's engaged to stuffy professor James Moreland. Fortunately, her uncle likes Ed, and he and his friends scheme to make her fall for Ed. The comedy in this movie stems from the fact that her uncle is none other than Albert Einstein, who's portrayed as a fun loving humble genius, as are his mischievous friends, Nathan, Kurt, and Boris.
