The Evil Tenant (2018)

Jim is a young writer who downsizes to a smaller apartment with his girlfriend Maria so that she can afford to support them while he pursues his big break: crafting a television pilot at the behest of his dynamic new manager. Once moved in, Jim settles down to write but finds himself distracted by Danielle and Reggie, an inconsiderate young couple living in the apartment below. Jim's distraction turns into an obsession when he becomes sure that Reggie is deliberately antagonizing him. Before long, Jim is at the end of his rope, and decides to take drastic measures to achieve his desired peace and quiet.
