The only way for him to survive is to become a Grim Reaper, a hunter of souls—with one harsh condition: not to get involved in an investigation that almost cost him his life. Chon Songmin agrees, seals the deal with a handshake with the Higher Powers—and in the very next second decides to play against the rules.
Trying to solve a series of strange abductions, the detective Chon Songmin chases a suspect and suffers a severe injury, after which he falls into a coma. His chances of waking up are almost nonexistent, but unexpectedly, he is offered a chance to return—though he’ll have to pay for it.
The Higher Powers give Songmin a new role: the Grim Reaper, a guide, and a hunter. He is willing to accept any terms, as long as he can be among the living again and reach the abductor—but the contract has a clause that ruins all his plans: he is absolutely forbidden from interfering in the affairs of his “previous” life…
Songmin accepts the offer, but secretly decides to take a risk and finish the hunt. Now he goes all in: he must simultaneously carry out the duties of a reaper, figure out the criminal, and not expose himself by breaking the contract—because he has gone exactly where he was strictly forbidden to go.
