Titling his directorial debut Ong-bak 2, the martial arts superstar from Thailand presents us with a story that has no relation whatsoever with the original: Tien (Jaa) is the son of a military commander, out to avenge his parents’ murders in the Ayutthaya Kingdom of 15th century Thailand. Barely avoiding a life in slavery, Tien is adopted by a camp of bandits, taught martial arts, and groomed as their new leader.
