Remake of the Philippine horror film of the same name. Bobby Winterhouse, who had just been released from prison, moved into the old apartment No. 509 left by his deceased mother. He hoped to have a new start in his life. He always heard all kinds of strange noises in his room. And he was the only one who could hear them. No one heard these noises, no one believed him, and no one could be trusted. All kinds of weird things happened one after another. What happened here in the past?
