The series started off with the Bak family being hunted down by the people of the martial arts world. They are a well-known family and consist of 5 members: the father--Bak Fung Tin, the mother, and their 3 children: Jin Man, Yuk Ying, and Jin Mo. Fung Tin was said to have murdered the leaders of 4 powerful sects, so the head of the martial arts world ordered that his whole family be killed.
