A former Olympic taekwondo gold medalist and three-time World Taekwondo Championship winner, Seong Han Su is a legendary martial artist known for his exceptional talent. Once the pride of Korean taekwondo, he now runs a neighborhood taekwondo academy, where he dedicates himself to teaching children.
Years of martial arts training have given him remarkable composure, but the one thing that continually tests his patience is his troublemaking son, Tae Hun. When Manager Kim tells him that Min Ji has been kidnapped, Han Su immediately joins the search. As a father himself, he cannot ignore another parent's desperate fight to save their child.
