"I'm 444, the best there is in business."
Han Moo-gang is a new detective who, outrageously ironic but effectively funny, can’t handle the sight of dead bodies and pools of blood.
Detective Han meets Ha-ram who tells her that her ability is not something to be scared about. The two decide to work together to save lives. But just as when they were set to start their mission, Detective Han is shot dead.
"My job is collecting human souls, humans calls us grim reapers."
Grim Reaper 444, one of the underworld’s most unsympathetic soul collector, takes over Detective Han’s body and makes him rise from his death bed. With a new soul on his body, Detective Han becomes cold hearted, ill-tempered and gutsy – all that the original Detective Han was not before a bullet hit his head.
444 or Black ends up falling for the half reaper girl, and finds out who he really is before his demise.
