Isolated (2022) Plot Summary & Ending Explained

Realising the danger, Rose pretends to comply with Peter’s demands while secretly preparing his morning meal. She crushes the beads of the rosary her mother gave her—made from the poisonous Rosary Pea—and mixes the toxin into the food. When Peter collapses from the poison, Rose finally feels the weight lift from her shoulders. The lingering spirits point her to the secret stash where the frozen bodies lie, exposing the full extent of Peter’s crimes.

The police arrive shortly after, discovering the victims’ corpses and the collection of newspaper clippings that Peter had kept as trophies. They identify him as the Owl Killer, but when they search the villa they cannot locate his body. Rose is taken to a hospital, where detectives inform her that Peter may still be alive. The film ends on this unsettling note: the killer’s fate remains ambiguous, leaving Rose—and the audience—to wonder whether the horror truly ended or if the owl’s echo will still haunt her future.
