In the film, Tien trains himself in martial arts, where he becomes a lethal soldier and sets out to avenge his parents' death.

In 1431 Siam, during the reign of Borommarachathirat II of the Ayutthaya Kingdom, Tien is the young son of a noble family, whose father Lord Sihadecho sends him to learn dance in a remote village under Master Bua instead of making him a warrior.

Although the young Tien disdaines their peaceful life, he eventually befriended an orphan girl named Pim.

After a dance coincidentally performed by a grown-up Pim, Tien sneaks in dressed as a khon dancer himself and attacks Rajasena, apparently cutting the treacherous lord down.

However, Tien meets his match at the hands of a final opponent named Bhuti Sangkha ("Crow Ghost"), a sinister yet formidable martial artist.

In a voiceover, Tien suffers this fate due to his bad karma, but adds that he will find a way to cheat death.

An ambiguous scene shows Tien with a fully-grown beard standing in front of the Ong Bak Buddha statue.

Famed Thai action choreographer and Jaa's mentor Panna Rittikrai was brought onto the project in the capacity of director to help complete the film.

The deal was negotiated by Tom Quinn, Senior Vice President of Magnolia, with Gilbert Lim of Sahamongkol Film International.

The site's consensus reads: "It suffers from comparisons to its predecessor, not to mention Tony Jaa's less-than-nimble direction, but Ong Bak 2 has all the extravagant violence and playful style that fans of the original will expect".

Jaa also showcased weapons such as the ninjatō, katana, jian, dao, talwar, nunchaku, rope dart, and three-section staff.

Various versions with regional subtitles and dubbings were released throughout Asia, South America, Australia and New Zealand in the months shortly after the film's premiere in its native Thailand.
