No institution, political view or tradition is safe, as Orton focuses his wicked sense of humour on a range of targets, including the establishment, an ex-Prime Minister, cross-dressing, misogyny and the medical profession. He brings together an array of distinctive characters, placing them in a series of improbable situations, unflinchingly exploring comic territory few playwrights before or since have dared to visit.

Within the pristine walls of his private psychiatric clinic, Doctor Prentice is interviewing a new secretary. Geraldine wants the position but seems underqualified and uncertain about her parentage. Mrs Prentice appears, flushed and in urgent need of a drink, following an illicit encounter with Nick Beckett, blackmailer and bellboy at the Station Hotel. In the meantime, Doctor Rance, a Government Inspector and Sergeant Match, a policeman, arrive amidst increasing chaos with searching questions of their own.
