Nathan is used to being in a rut. The same dead-end job, the same nagging wife and sexless marriage, his only solace, the bottle. But now he is reliving the same day, over and over again. Thrust into a bizarre nightmare, frozen in time, he eventually snaps and lashes out at the shrieking harpy, oftentimes at his back. She is injured and bloodied when he leaves, but then, waking up in the same strange hell, it is morning again and she is uninjured, still griping at him, as if nothing happened. The realization is liberating.
His actions no longer have any consequences. He gets to kill his wife a multitude of times and in a myriad of ways. She is shot, bashed, stabbed and strangled, each violent murder cramming him with a joy he never knew. He even tears up her limp corpse, eventually inhaling a blast inside her, after years of her never in the mood. How long will this last? No one knows, but he'll have something to occupy himself with for a long time.
