To entertain the prisoners, Jung Ba Reum and his childhood friend, Koo Dong Koo (Woo Ji Hyun), tried to perform magic on stage. He called a volunteer in the crowd to experience the magic. When the person already got in the metal box, Jung Ba Reum began to spin the box.
And when he finally opened it, everyone was shocked to see a naked body of a man covered in blood.
It was then identified that the man was Na Chi Kook (Lee Seo Jun), Jung Ba Reum's friend. It was revealed that it was the police officer behind the incident.
