Gregory La Cava directs Mary Astor in this wise and witty drawing-room war of the sexes, in which manners never falter while scandal simmers at the surface. Mrs. Nancy Gibson (Astor), on a return cruise to the States after a long absence, makes the acquaintance of Sir Guy Harrington (John Halliday), Europe's richest and most wanted bachelor. The smooth Sir Guy is besotted with her, but Nancy has only thoughts for the husband waiting for her return. Unfortunately, husband Donald (Robert Ames) has "gone off the deep end" for his new mistress Peggy Preston (Noel Francis), as she is quickly informed by Donald's partner and brother-in-law, Billy (Edward Everett Horton). Back at Nancy's country estate, Donald finds his divorce demands easily accepted, with one proviso - he agree to have Peggy and her mother (Gladys Gale) join them for the weekend, along with Nancy's (faux) new lover - Sir Guy Harrington!
