Amelia goes to an abandoned mental hospital in search of answers about her deceased twin sister — tracing her sister's footsteps through a building that once conducted horrifying experiments and has not grown any less oppressive since. The silence and darkness of the hospital close around her immediately. As she moves through the corridors, she encounters faint screams, ghostly shapes, figures that resemble her sister and then vanish. She searches the hidden rooms, the locked laboratories, the clues embedded in the institution's history. The deeper she goes, the more her own mind becomes part of the mystery — the line between memory, delusion, and the actual present growing harder to locate with each step.
