Two sisters are in search of their grandfather's body so it can be buried in their family tomb. In the jungle, they run afoul of gangsters performing an evil experiment involving blood that turns them into zombies. A Sword of God may be involved, a bunch of exorcists and zombie attacks are also involved. Also, the zombies know martial arts.

Brilliant action from the Ong Bak master as he faces gangster's, crocodiles and a whole lot more on the river of fire. Long live Panna.
