Warriors Within 2

50 years ago, a match between a Chinese and a Japanese karate expert ended in a dead heat. Together, they wrote a martial art book that has caused storms across the martial art world ever since. In 2019, Chong Wai fights hard and defeats her Japanese rival to win her first karate championship. However, the match leaves her seriously injured. Meanwhile, in Japan, Saori Kisaragi goes through hardships and is shunned by her teammates because of the martial art book. When she learns of Chong, who has defeated one of her senior clan members, she travels to Hong Kong to challenge Chong and to find the book. When the Hong Kong karate team withdraws from the Tokyo Olympics, Chong is devastated as she feels that her years of training are wasted. She stays away from all things related to karate while her friend Chi Ho manages the dojo, hoping for Chong to return. Chong finds an office job and meets her boss Darwin, who takes good care of her. On the day Chong packs up her personal belongings at the sport institute, Kisaragi comes and challenges her. Chong's teammate Tin Oi fights on her behalf and is instantly defeated. Chong is dumbfounded. Kisaragi throws down the gauntlet before she leaves.
