In the enclosed, insulated world of a London flat the only intrusion into which is a brief outburst of demonstrators' voices against the Home Secretary who lives nearby are worked out the permutations and combinations of Ann and her two lovers.

Dave, her previous companion, a journalist, has been away and on returning finds that he has been replaced by Patrick, a conventional man of the office, amiable but dull. Though Ann rules the roost, she herself is weak enough to be unable to do without one of them; and in the end Dave is reinstalled and Patrick dismissed. But how long this will last is anybody's guess.

In three of the nine scenes the stage is occupied by each of the three characters alone; so that a glimpse is afforded of their behavior during their unobserved and private moments, to be set against the pattern of their interchanging relationships.
