No Exit (1959)

In a locked room with forever burning light, a man and two women meet after their death: Garcin has tormented his wife to death and failed cowardly in a crucial situation. The lesbian Ines has alienated a young woman from her husband, the woman has poisoned herself and Ines with gas. Estelle has murdered her child and drove the lover to death. These three sleepless stew in a hell that consists not of fire, but of cosy sofa places where they have to sit forever and torment themselves forever. And they can't even kill themselves - they're already dead.
