Set in an apartment building whose occupants include Arthur Earthleigh, a meek and mild type married to the beautiful-but-domineering Mae; a Bohemian artist, David Galleo and his always-there model, Deborah Tyler; and Olive Jensen, a Greenwich Village type who is always slightly-but-continuously inebriated, and whose motto is "love and let love." She calls on George while his wife is out, and when she passes out during his attempts to get her out before his wife returns, he thinks she is dead and deposits her on Galleo's terrace. Galleo takes advantage of the situation by using it in a blackmail scheme against Arthur, which is shaky, at best, as Olive refuses to stay dead.
Amanda and Elyot are one another's former spouse. Elyot is remarried to Sibyl and Amanda married Victor. Unexpectedly, both honeymooning couples arrive at a hotel on the same day and are put in rooms with adjoining terraces. Things go well until Amanda sees Elyot on the adjacent terrace.
