It was supposed to be a simple execution. R (Don-yun Yu), son of Korean immigrants raised and living in Japan, would be executed by way of hanging by a group of Japanese law enforcement officers. Seems like a foolproof way to kill somebody but once the lever got pulled and the hanging was executed, it turned out R wasn't dead, he was surely alive. In fact, he was not just revived but he had total amnesia about his life up to that point. Now all the powerful members of Japanese society tasked with killing R are stuck in a conundrum; can they re-kill a man, especially one who is now a shell of the former murderer? They all decide to give it their best go in restoring R's memory so that they can kill him and restore their sense of warped justice.
