Sun Dragon (1979)

Sung Shao Chong (Billy Chong) journeys through the Arizona desert, lending a hand to those in distress as he heads to reunite with his friend Kum (Lam Hak-Ming) in a small town. Upon arrival, he confronts a gang that terrorizes the community and extorts local businesses. Meanwhile, three bank robbers hide in town after a heist, brutally killing a black farming family and leaving only the injured eldest son, Tommy (Carl Scott), to escape. Rescued by Chong and Kum, Tommy learns kung fu from Doctor Ko (Leung Siu-Chung) and seeks vengeance, aided by Chong, who also targets the criminals.
