The game revolves around a man named Sissel who wakes up to discover he's dead, having no memories of who he was or why he was killed. The only clues pertaining to his death and his true identity are a young detective named Lynne and a near-sighted assassin named Jeego. Sissel eventually learns that, as a spirit, he has the power to possess inanimate objects and travel back to four minutes before a person was killed in order to change his fate. However he also learns that when the sun rises in the morning, his soul will disappear forever. Whilst trying to figure out the mysteries surrounding his memories and death, Sissel decides to use his ghostly powers to protect other people from suffering the same fate he did.
