On a dark and stormy night, a group of young people embarks on a journey to an old abandoned sanatorium, a place surrounded by urban legends and chilling myths. Their youthful curiosity drives them to explore the unknown, but what begins as a night of fun quickly turns into a struggle for survival. During their stay, they discover an ancient summoning game that, unknowingly, awakens a malevolent entity that has been trapped for decades.
As the hours pass, the group begins to experience supernatural phenomena, and one by one, they start to disappear under horrifying circumstances. Delving into the heart of terror, the friends are forced to confront their own fears and secrets while trying to decipher the rules of the macabre game they have unleashed. With the pressure of time mounting and tension between them rising, they realize that they are not only fighting against a dark force, but also against the distrust that begins to erode their bonds.
With a fast-paced rhythm, this psychological horror story explores the fragility of friendship and the struggle between good and evil. Each deeper step into the sanatorium seems to bring them closer to a terrifying truth: some games are meant to remain unplayed, and crossing that line often comes at a steep price. The night looms over them, and when the midnight bell tolls, not everyone will make it out.
