Return of the Bloodthirsty Police

Bi Gwang was taken in by Bo Sal, a monk from Hwaguksa Temple and leader of its assassin organization, who raised him to become a skilled killer.
After years of carrying out missions, Bi Gwang grows tired of violence and chooses to leave the group to pursue an ordinary life.
However, his former allies betray him and take his life when they refuse to let him go.
After his death, Bi Gwang’s soul awakens inside the body of a police officer named Kim Gyeongsu.
Given a second chance, he vows to uncover the truth and take revenge on the Hwaguksa group for their betrayal.
