Blood of an Indian Fetish Cult (1984)

A cult of chinese youths, who idolize American Indians, retreat into the wilderness where they build a Jonestownesque reservation. Their religious rituals soon get out-of-hand and, at one point, the priestess "loves" her mate to death. Surrounding the ceremonies are a series of goofy vignettes including a martial-arts fighter who strenghten his penis by slamming it into a tree truck!
