The play is set in the Harrington family's weekend cottage in
Suffolk. Stanley Harrington is a self-made and extremely prosperous manufacturer of furniture. He is wary of culture and cannot understand his son, who has just become an undergraduate at
Cambridge. Both the father and son feel isolated and are unhappy. Clive recoils equally from the boorish attitude of his father and the suffocating excess of maternal love from his mother. Louise Harrington is a social and intellectual snob who dabbles in culture. Pamela is a fairly cheerful and relatively normal schoolgirl. Walter, Pamela's tutor, is the catalyst bringing the family's suppressed resentments to the surface, leading to frank exchanges and potential reconciliation. Louise blames Stanley for suppressing her creative aspirations; Stanley pooh-poohs Clive's pursuit of a meaningful life beyond the family business; Pamela believes Clive is over-indulged; Clive feels unappreciated and misunderstood. Walter, who has fled from Nazi-sympathising parents, is grateful for the security and acceptance he has found with the Harringtons. By engaging with each family member, Walter helps them gain a perspective on the issues facing each of them, guiding them towards resolution. He exemplifies the qualities to which Clive aspires: independence, education, self-sufficiency, and artistic inclination, balanced by self-acceptance. Tensions increase when Clive, envious of his mother's fondness for Walter (to whom he feels a half-suppressed gay attraction) mendaciously tells Stanley that Louise and Walter are having an affair. In fact Walter is seeking a mother-substitute rather than a lover, although Louise has other ideas. She turns against Walter and insists on his dismissal. His pleas to remain with the family are rebuffed. Louise discovers Clive's deceit and spurns his apology in a heated argument. In a dramatic climax Walter attempts suicide by gas inhalation in his bedroom. The family members rally to save him, recognising the profound impact he has had on their lives. They successfully revive him and the play concludes with Clive praying for courage for all of them. ==Revivals and adaptations==
