French Dressing(1927)

Philip and Cynthia Grey are a pair of recently-wed Bostonians, and Cynthia is properly back-bay no-action quiet and dowdy, and Philip resigns himself to the quietness (no action) regularity of their home. But then along comes a blonde, Peggy Nash, who adds some action and outside-regularity to Philip's life. Cynthia is somewhat upset at this turn of events, and decides to go to Paris - the Wickedest City in the World - and get a quiet divorce. Cynthia soon finds out that Paris is a really gay city, especially after Henri de Briac, shows up and offers to be her guide to the delights of Paris (primarily him). Cynthia quickly sheds some of her dowdy ways and dowdy clothes, and is having herself what was once quaintly described as a gay old time. Philip then shows up in Paris, deciding he wants Cynthia back as his wife, and Peggy shows up right behind him and, soon, it is up to Henri to make the pairing-arrangements for the foursome.
