After a shootout with dozens of assassins, Wong Kom, bodyguard to Chot Petchpantakarn, the wealthiest man in Asia, finds his client killed.
Chaichol, the son and heir to the family fortune, fires the bodyguard and takes it upon himself to find the killers. He's then ambushed, and the rest of the bodyguard team is wiped out. Chaichol, however, comes out of it alive, and finds himself in a Bangkok slum, living with a volunteer car-accident rescue squad and falling in love with tomboyish Pok.
Meanwhile, Wong Kom is working to clear his name, and stay ahead of the chief villain and his bumbling gang of henchmen.
Some of the film's promotional materials imply that this follow-up to Ong-Bak: Muay Thai Warrior starring Tony Jaa. In fact, Tony only has a small (but still memorable) role as an anonymous fighter in a supermarket.
In addition to Tony Jaa, dozens of Thai celebrities, including sports figures, comedians and musicians, have roles and cameos on the film. Among them are:
Surachai Juntimatorn, portraying Chaichol's father, is more popularly known as "Nga Caravan" of the pioneering 1970s songs for life band, Caravan.
Yingyong Yodbuangam, who portrayed one of the leaders of the bad guys, is a well-known luk thung singer.
