Kham (Tony Jaa) has resumed a quiet village life with his “brother”/elephant, Khon, back in Thailand. Job, an oddball who loves playing with electrical devices, has lived in the village for some time and has earned the trust of the locals. Unknown to Kham, he’s an agent of an arms dealer known as Mr. LC (RZA). A fan of Kham’s exploits, LC had Job keep tabs on Kham without his knowledge. Things change for Kham when a merchant, Suchart Vilawandei (Adinan Buntanaporn), wants to buy Khon, but Kham refuses to sell Khon. Suchart gives his business card to Kham in case he changes his mind.
While eating with the local villagers, Kham feels something is wrong and returns home to find that Job has been beaten and Khon has been taken by Suchart. Using the business card that Suchart gave him, Kham goes to Suchart’s home to get answers but only finds that Suchart has been killed moments earlier. Suchart’s two nieces, martial artists Ping-ping (Yanin “Jeeja” Vismitananda) and Sue-sue (Theerada Kittiseriprasert) arrive and believe that Kham must be responsible. The two attack him, but he evades and escapes; the authorities are alerted and the police give chase.
While running from the law, Kham encounters Mark, who fakes being assaulted and allows Kham to escape. Later on, they secretly meet to learn more about the situation. Mark himself is in Thailand on a job for Interpol investigating a recent terrorist plot involving the peace talks between East Katana and West Katana in Bangkok.
