A Hong Kong variation on Robin Hood. The corrupt officials of a Chinese village are continually robbed by a masked bandit know as "Iron Monkey" named after a benevolent deity. When all else fails, the Govenor forces a traveling physician (Donnie Yen) into finding the bandit. The arrival of an evil Shaolin monk, brings the Physician and Iron Monkey together to battle the corrupt government.
A masked bandit know as "Iron Monkey" steals from the corrupt authorities as a masked thief to give to the poor while another martial artist/doctor is forced to hunt him down. But a major threat unites them as a powerful and traitorous shaolin monk takes over the authorities.
