When the British captain Peter Bain is busted for trying to sell defective firearms to influential Chinese non-timber forest product trader named Yang.
Forced to hunt wild game with these firearms along with Yang's men, Bain links up with ex-monk Wan and Karen-American female guide and hunter Julia, who he meets on the way to the jungle.
The group sets off to hunt a long-tusked elephant, said to be protected by a demon tigress that can transform itself into a woman.
The tigress is supposedly possessed by the revengeful spirit of Nian, a young woman who was tortured and killed in the King River Battle near the Three Pagoda Pass almost a century earlier.
Tigress of King River is the final work of veteran filmmaker Bhandit Rittakol with a prolific career in the 1980s and 1990s.
