A pair of shipboard smugglers have a large diamond hidden inside a small elephant statuette, which they plant on absentminded Lord Epping to get it past customs.

Thanks to flirtatious Diana's efforts to get the elephant back, the comic confusion proliferates, with 'spitfire' Carmelita (now a blonde) playing a prominent part.
