Great Challenge, The (DVD)

A Mortal Fighter. An Eternal Combat.

A group of highly accomplished and fearless athletes, whose breakneck skills include leaping from rooftops and scaling vertiginous facades, goes to Bangkok to set up a gym and explore the cityscape.

But once there, they encounter a gang of Thai athletes, who, betraying their own heritage, have pledged an allegiance to the Japanese Yakuza aiming to destroy the local triad and gain control of the city.
