Set in Princeton, N.J. in the mid-1950s, the scientific genius Albert Einstein is cast in the role of a most unlikely Cupid when his brainy niece, Catherine, becomes engaged to an equally scholarly but conniving psychologist. Foreseeing a bleak future for Catherine if she goes through with the marriage, Einstein decides to find his niece a new and truer love. Though Catherine is determined to marry a genius like her Uncle Albert, it is Ed, a grease monkey at the local garage, who strikes Einstein as his niece's proper match.
