Despite their small size and inexperience, having grown up under the roof of a Muay Thai school two young brothers and their friends have become highly skilled, if undisciplined, martial artists. Sadly, the youngest of the gang suffers from an acute heart condition, which following a minor scuffle with some local bullies lands him in hospital and desperately in need of a life-saving transplant. Fortunately, a viable heart soon becomes available at another local hospital, but before it can be transferred the building is overtaken by rebel soldiers-turned-terrorists prepared to kill if their politically-driven demands are not met by the authorities.

With only four hours in which the surgery can be performed successfully, the young friends take it upon themselves to infiltrate the hospital and retrieve the donated organ. Armed with only their martial arts skills and the will to save their friend's life, this small group of mini Muay Thai marvels embarks on a desperate race against time in which they will be forced to defy danger, confront an army of terrorists and make an heroic bid to overcome insurmountable odds.

OK, the expected mix of hokey plotting and eye-watering sentimentality aside, Force of Five (which is you want to look it up elsewhere is actually titled 5 huajai hero and has the somewhat less imposing international title of Power Kids - yike!) does have a notable pedigree, being produced by Prachya Pinkaew, Panna Rittikrai and Sukanya Vongsthapat, the creative forces behind such Thai action movie hits as Ong Bak, Warrior King, Raging Phoenix, Born To Fight and Chocolate, and is the directorial debut of Krissanapong Rachata. It also had the jump on a certain recent western action movie of note with the concept of foul-mouthed youngsters who can, as they say, kick ass.

Force of Five will be released on UK DVD and Blu-ray on 5th July 2010 by Cine Asia at the RRP of £17.99 for the DVDa and £24.99 for the Blu-ray. It's being labeled an 'Ultimate Edition', but I'm not sure the listed special features justify that one:

• Interview Gallery;
• Making of featurette;
• Behind The Scenes featurette;
• Original Trailer.

The soundtracks on offer will be Dolby Digital Thai 2.0 and 5.1 on the DVD and DTS HD MA Thai 5.1 on the Blu-ray, plus optional English Subtitles.
