Beautiful socialite Audrey Swallow likes doing favors for friends - and she owes a big one to Lucy Darling, her look-alike pal from college. So when Lucy begs her, Audrey agrees to impersonate Lucy on the job for two days. There are only three complications: first, Lucy 'works' as a high-class call girl. Second, the two days have to be spent in Monaco. Third and finally, Audrey has to get back to New York in time for an engagement party - her own! But what are friends for? And when Audrey is delayed getting back, Lucy has to do some entertaining on Audrey's behalf - and, as Audrey discovers, Lucy can be very entertaining.
A pair of identical women, a high-priced call girl and a wealthy socialite, decide to switch lives for a wild weekend. Carol Levy plays both roles.
