Loose musical adaptation of J.M. Barrie's "The Admirable Crichton" with the butler transformed into singing sailor Crosby. Fabulously wealthy heiress Lombard invites her pals for a South Seas yachting adventure. Only the ship gets wrecked and everyone winds up on a small island where the practical Crosby whips everyone into shape (and romances Lombard). Burns and Allen supply additional comedy as a pair of botanists who just happen to be studying the local fauna.
