A group of travellers are trekking through the exotic forests of Thailand when from out of nowhere comes a martial arts maniac who hacks up most of the party with a multitude of deadly weapons and savage martial techniques. The mad man is the Spirited Killer, a forest dweller who will kill all those who enter his domain.

Leading those who survive this vicious attack is Tony Jaa, making his film debut, taking on the might of Thai action star and mentor Panna Rittikrai as the Spirited Killer. The action stakes the action stars and stunt teams give Jackie Chan and Jet Li a run for their money. This is the first picture from the team who would later bring the world "Ong Bak" and "Tong Yum Goong".
