Tony Jaa is the leader of the Panter Squad - a group of martial arts madmen employed by a notorious General and Cartel kingpin on the border of Thailand and The Golden Triangle. They have kidnapped a noted Explorer who has been searching for an ancient priceless artefact that the General is desperate to find and profit from. A team of ruthless mercenaries leads a crack team to free the Explorer, crush the General and deadly Panther squad. But before doing so they must overcome the fearsome Black Goblins and the crazed Kung Fu Zombies.

The policeman Pitak (Jan Janmulltree) switches from a band of thugs. Only the leader (Panna Rittikrai) survived - and vows revenge. With the help of his protégé (Tony Jaa), he sets out to terrorize the cop. Who is now staying with his family: his widowed dad, who is also a policeman, his younger sister Ann and brother Lau. They all float now in mortal danger.
