Nearly 7-foot-tall Australian Nathan Jones stars as gentle giant Barney Emerald, who’s mugged and robbed on a vacation trip to Thailand and ends up being rescued and taken in by two Thai sisters in this comic martial arts saga. One of the sisters, Dokya (Sasisa Jindamanee), is a champion in the art of muay thai kickboxing, which Barney eventually learns and uses — with the girls' help -- to take revenge on the thugs who robbed him.
