Ga-Jang No is a strong, dedicated, and humble man, with much respect for the martial arts. After the death of his lovely wife, this muscle-for-hire just wants an easy job that allows him to be a good father to his three little babies. He’s even happy to pull guard duty and fend off amateur fighters if it means he can return home safely each night. But when a creepy cult starts stealing children from the city, Ga-Jang must step up to the challenge and discover his true warrior potential.
