Recollections of a Person Who Wasn't Real

Photo restorer Minh An finds an old photograph of himself twelve years ago beside a girl he has no memory of, with a warning written on the back: "Don't let him go alone." Following the clue with a friend, he uncovers a mysterious archive, flooded tunnels and memories that someone has deliberately erased. The closer he gets to the truth about Lam and Van, the more he must question who was saved, who was forgotten, and whether the girl in the photo was ever real.
