The story starts with a man whose wife just died, and his daughter was kidnapped and murdered. He became depressed after that. Once in his sleep, he saw a dream. There was a dark room with a small light glowing not very far. He hears a voice that tells him about, that his daughter is stuck in Limbo,tells him about a number (which appears to be a date) and a mysterious place. When he wakes up, that same number was written on his left hand. But it was permanent. He researches a lot about them all. Then with a lot of adventures (and nightmares!), he finds a way to Limbo, and tries to save his daughter.
