A teenage girl moves with her parents into a cheap house in another city. While unpacking, she finds an old photograph of a cute girl her age appearing in the mirror and keeps it beside the mirror. The girl was murdered at a house party, her case went cold, and her ghost remains trapped between life and eternal rest. As the protagonist gathers clues to identify the killer, she and the ghost grow close and romantic tension builds, despite the ghost’s cold, untouchable body. When the killer is finally exposed, the ghost finds peace, leaving behind a love letter promising that perhaps they can be together in another life.
