Jeremy and Celia return a week early from their unsuccessful honeymoon to find that both Jeremy's working partners have accepted his offer to stay in his house while they are away; the only problem is they have bought the other's wife with them.
Jeremy discovers one illicit couple, Celia the other, and both issue invitations to join the newly-weds for dinner. Complications pile up thick and fast as, realizing their dilemma, and desperate to make a good impression on Jeremy's colleagues, the couple have to stage two dinner parties - simultaneously!- one on the patio and one in the dining room.
