A group of friends are enjoying their high school days until their friend Ava vanish without explanation. Her family and friends are worried; they think she was kidnapped or committed suicide, or maybe something worse, but there's no trace of her body. Even the police can't find clues about her whereabouts, but Louise suspects that something has to do with Ava's disappearance at the school. She suspects there is a secret in the school and with the old principal. When they found the truth, they searched everything and investigated, and they decided to explore a school in the middle of the night to search for Ava. Maybe she waited for us to rescue her, but they might face an unexpected fate. In the end, is Ava rescued, or is she still missing?
