A friendly giant unlocks his untapped Muay Thai fighting skills, and teams with two young girls to take down ruthless Pattaya crime syndicate. Barney Emerald (Nathan Jones) was on holiday in the Gulf of Thailand when he was drugged, and his passport was stolen. Thankfully for Barney, a young, English speaking Thai girl and her tough-as-nails sister -a Muay Thai kick-boxer - agree to take him in until he can find a way home. Then one day, while dining at a restaurant owned by the girls' mother, Barney takes a taste of spicy somtum, and goes completely berserk. Now, every time Barney takes a taste of tam bak hung, he unleashes a virtual firestorm of martial arts fury. Realizing that Barney could be the key to taking down the city's biggest crime boss, the sisters guide him directly into the heart of Pattaya's criminal underworld, and provide him with all the somtum he'll need to topple an entire criminal empire.
