Plot summary

Paleontologist David Huxley hopes to get a $1 million donation for the Museum of Natural History and in the process meets the potential benefactor's niece, Susan Vance. David is engaged to his assistant Alice Swallow - he's getting married the next day - but that doesn't stop Susan who decides she has met her man. Susan and David are a study in opposites - he the serious, bookish scientist and she the madcap heiress. Mayhem ensues when a leopard Susan ordered as a gift for her aunt arrives and is then confused with a similar-looking but quite dangerous leopard that escapes while being transported from a local zoo. This is only the beginning of their day together as further mix-ups add to the hilarity.—garykmcd
