Beggars of Bangkok (1978)

One day, the beggar empire of Chao Pho Ngo is thrown into turmoil when the Tai Ko beggar gang attempts to overthrow his operation and murders one of his men. Chang, Chao Pho Ngo’s most skilled beggar, rallies the others to launch a decisive attack against the Tai Ko group— even if it means killing one another to the last.
