A jury finds Adam Grant guilty of murder, and the judge sentences him to death. Grant laughs with despair, then exclaims that he refuses to die again. He frantically tries to tell those present – including district attorneyHenry Ritchie and newspaper editorPaul Carson – that he is dreaming, and if he is executed they will all cease to exist. Locked up on death row, Grant describes the experience of dying in the electric chair, from the perspective of the condemned, to a fellow prisoner in chilling graphic detail. Later, a drunk Carson shows up at Ritchie's house. He has been speaking to Grant, and fears the convict might be telling the truth. He argues that their lives seem impossibly perfect, and encourages Ritchie to explore his own doubts. Ritchie's wife Carol, annoyed by Carson's outburst, goes to bed early, telling her husband that there are steaks almost ready in the oven. Back at the prison, Grant waits for Ritchie to arrive as usual, noting the implausibility of his fellow inmate Jiggs having a watch to tell him the time. Ritchie comes, and they have a conversation Grant has had many times before with other DAs, enough times to mouth the man's words as he says them. He points out as an example the implausibility of the DA coming to visit like this. Ritchie asks him why he cares about dying if it's all a dream, and Grant explains that he's tormented by having this same incredibly realistic nightmare every night. As Ritchie leaves, Grant tries to prove that they're in a dream, by predicting that the steak Ritchie's wife had cooked for supper will now be something else. Ritchie rushes home, and finds a roast in the oven. Jiggs suggests to Grant that he try to get a psychiatric exemption from execution. To prove his sanity to Jiggs, Grant points out logical errors accepted as normal by those around him, such as the fact that his trial and execution are happening on the same day, and the fact that the prisoners perfectly fit the stereotypes Grant would come up with from movies. Meanwhile, at Ritchie's home, he and Carson watch the approach of midnight, debating the unlikelihood that the execution time matches the one shown in movies. As Grant waits to be taken to the electric chair, Father Beaman visits him. Grant vaguely recalls him as a real priest who died when he was a boy. He further remembers that Carson is really the young priest who replaced Beaman, but struggles to place Ritchie. Carson finally persuades Ritchie that either Grant is right or he's insane, so he calls the governor for a stay of execution. But the call comes seconds too late, Grant is executed, and the world blinks out. The lights come up and Grant finds himself back in the courtroom, just as at the beginning. He is being convicted and sentenced to death for murder, again. The same people surround him in the courtroom, but their identities and roles have changed. The story begins to proceed as before.
