The sequel to the cult classic August Underground is a character study in the sick, an amoral putrid fantasy. The found footage contained in August Underground’s MORDUM documents extreme deviant sexuality, torture and murder, while unfolding a classic tale of a man and woman in love. However, the woman cannot give up her other lover, who also happens to be her younger brother. August Underground’s MORDUM will vomit all over you and leave you for dead!
