Return of the Bloodthirsty Police

Bo Sal, a monk at the Hwaguksa Buddhist temple and head of the Hwaguksa hitman group, picked up Bi Gwang as a child and raised him as a hitman. When Bi Gwang grew tired of the killing and decided to leave the group to start living a normal life, Bo Sal and the other members of the Hwaguksa group betrayed and killed him.
