No Exit is a 1944 existentialist play by Jean-Paul Sartre, originally published in French as Huis clos (In Camera). English translations have also been performed under the titles In Camera, No Way Out, and Dead End. No Exit was first performed at the Vieux-Colombier on May 27 1944, just before the liberation of Paris in World War II.
The play features only four characters (one of whom, the Valet, appears for only a very limited time), and one set. No Exit is the source of the famous Sartrean maxim, "Hell is other people." It has been adapted in cinema many times, notably in 1954 by Jacqueline Audry.
