It is a farce following the consequences of an adulterous affair between a married man and his boss's wife and their attempts to cover their tracks by roping in a third couple to be their alibi, resulting in a chain of misunderstandings, conflicts and revelations.
[2] The play has a cast of six: Frank and Fiona Foster, Bob and Teresa Phillips, and William and Mary Featherstone.
Teresa and Bob's conflict culminates in her throwing soup at him but mistakenly hitting William, while in the Fosters' dinner party, his drenched state is the result of a leak from the bathroom above.
After Frank invites everyone to his house to clear the air, William half-apologises to Mary, who chews him out over his controlling nature, but ultimately forgives him, while Bob and Teresa make up.
Assuming that he was the ghost caller, she suggests meeting him in private to discuss his problems, to which he bewilderedly agrees.
