Joker leads a double life. Boastful and talented in conversation, he is secretly a notorious thief wanted by the police. Using his exceptional disguise skills, Joker robs wealthy oppressors and redistributes their riches to aid struggling villagers. On the other side is Jack, an 18-year-old former substitute taekwondo fighter turned debt collector. With a calm and quiet demeanor, Jack instills fear in those he encounters. Despite his intimidating presence, he is a reasonable man who believes in solving problems without force and holds the conviction that "the strength one possesses should be used only to protect the weak."
