An Assassin is cursed by the souls of the people he killed in the past. Now, he is a Grim Reaper, a demon who receives constant punishments because of his sins. In this context, an Entity appears, a neutral being who oversees the Assassin's curse. Consequently, and on a journey to hell, both characters confront each other in a philosophical-moral debate about the meaning of forgiveness, the prison of guilt, and the existence of redemption.
