Run Rabbit (2018) Plot Summary & Ending Explained

The conclusion of Run Rabbit Run hinges on a shattering revelation regarding the fate of Sarah’s missing sister, Alice. Through a series of fragmented flashbacks, the truth emerges: Alice did not run away as Sarah had claimed for years. Instead, a childhood game turned deadly when a young Sarah locked Alice in a cabinet. After Alice retaliated, Sarah struck her with a rabbit trap and chased her to a cliff edge, ultimately pushing her sister to her death. This repressed murder serves as the psychological anchor of the film, explaining Sarah's deteriorating mental state and the sudden emergence of "Alice" in her daughter, Mia.

The film’s final moments depict a chilling scene where Mia walks hand-in-hand with a girl resembling Alice toward the cliff. While this ambiguous imagery invites a supernatural interpretation, the narrative framework strongly suggests this is a hallucination born of Sarah's overwhelming guilt. Throughout the story, the movie plants subtle clues that Sarah is an unreliable narrator. For instance, Mia’s teachers never mention the "Alice" persona, and Mia appears entirely unaware of the severe nosebleeds Sarah claims to see, suggesting these physical signs are merely projections of Sarah’s fracturing psyche. Furthermore, Sarah is revealed to be unconsciously drawing the disturbing images found in Mia’s belongings, confirming that her own mind is the source of the chaos.
