Chinatown Kid (1977)

"He was the Leader of the White Dragons... the Toughest Gang on any Turf!"

Struggling to survive the murderous gang wars of Hong Kong, Tan Tung, a young martial arts street fighter, successfully takes on all challengers—until he runs up against the savage underworld empire of Hong Kong's Triad mafia. Escaping to San Francisco, he again tangles with criminal gangs, but this time fights his way to the top of the city's most feared gangster organization led by the White Dragon boss.
