Finn the human, one of the greatest heroes in the land of Ooo, is alone; in a new, unsuspecting world with none of the hardships and pain from his own. He must find a way to fight his past and prevent the arrival of a force; strong enough to wipe out species from the face of planets. And he will do that by any means necessary, even if it costs him himself.
