Filmmaker Peter McCarthy was randomly attacked on a night out in Galway City (Ireland), leaving him badly scarred and threatening the vision in his left eye. On his recovery Peter came across an article on Muay Thai boxing in a newspaper and decided to leave Ireland for Thailand and learn how to defend himself. FIGHT OR FLIGHT documents Peter’s journey over several years in Thailand as he goes from novice in Muay Thai to fighting in semi-professional bouts in arenas full to capacity around Thailand. Through the course of his experiences in Muay Thai, Peter learns that behind his compulsion to fight lies fear and ultimately a deep-seated anger that has driven him to risk his body in the ring.
