Growing up in Chaiya, Surat Thani Province, three boys, Piak, Pao and Samor, are followers of Pao's brother, Krang (Prawit Kittichanthira), a legendary muay Thai fighter who is taught by Pao's father, Tew (Samart Payakaroon).
His Buddhist teacher, the famous monk Phra Buddhadasa from the nearby temple Wat Suan Mokkha in Chaiya, encouraged him to teach monkeys in a positive way, without the use of force.
