"No Exit" is a one-act play by the French philosopher and playwright Jean-Paul Sartre. It explores the theme of existentialism, focusing on three characters who find themselves trapped in a small room in hell. They soon realize that their eternal punishment is not physical torture, but rather the psychological torment of being forced to confront their own flaws and the truths about one another. The characters, Garcin, Inès, and Estelle, each bring their own baggage and secrets into the room. As they interact, they reveal their pasts and the reasons for their damnation. The famous line "Hell is other people" encapsulates the play's central idea: that our relationships and the judgments of others can be the most painful forms of suffering.
