The now‑retired banker Theo Conroy is married to the sought‑after actress Suzanne, and due to her busy schedule, the couple doesn’t spend much time together. When Suzanne has a break from filming, she and their six‑year‑old daughter go to relax in a designer mansion in the Welsh countryside, which they rented online. But the expected relaxation doesn’t happen: the whole family has nightmares, his jealousy towards his young wife intensifies, and Theo feels that something is wrong with the house.
