a single mom and her son and daughter and their hippie chick friend be camp in the wood . a muscle bound and machete wielding maniac in a yellow ski mask appear . he start terrorize and sexually violate the family before murder them with a machete . wet wilderness be load with ugly hardcore sex and force incest and blatant racism . it a politically incorrect a xxx roughies get . the score be steal from seminal hitchcock horror classic psycho and also jaw . the acting be hilariously awful and the editing be bad and there be some huge lapse in logic . the repetitive nature of the sex scene grind the movie after while so the brief running time be a blessing . the scene of violence be quite nasty for example the hippie girl be stab with the machete in her groin and one can see blood on her crotch . negative and that be generous .
