Summary Review
With a killer gorilla on the loose, a group of strangers find themselves stranded at a remote mansion of a grieving madwoman one dark and stormy night. They indulge in swapping bizarre personal backstories - and bodily fluids.
Imagine yourself a typical low-budget horror opening, in which random people gather around an old dark mansion during a nightly thunderstorm. They're all slightly eccentric characters with unusual backgrounds and/or odd
personalities and, naturally, the female owner of the mansion is the queen of all madness. Her guests soon begin to physically experiment with themselves and each other and these sexual outbursts become gradually odder.
Masturbation and ordinary hetero-sex at first, but before you properly realize it; you're up to your neck in gay sex, voyeurism, sex with peculiar attributes and even bestiality. This movie is available in two versions,
but I can safely say already that even the cut Theatrical Version (120 minutes instead of 150) is more than weird enough for every avid fan of offbeat cinema on this planet. Versions
