The couple in the movie cannot remember what happened a night before. They find a video that they took which shows them getting drunk, having sex, and the husband strangling his wife. She struggles to get away, but he pins her down and continues to choke her. Later in the movie, the woman is having an episode where she is unsure if she is hallucinating or not. During it, she is held down while an unknown/unseen something kept in a bag is held between her legs and it is implied that it crawled inside her. The next day she is revealed to be pregnant.
