A traumatic childhood experience has left attractive brunette Helen (Fiona Horsey) with serious intimacy issues, but matters are made much worse when she is raped by her boyfriend and finds that she possesses the sexual equivalent of the Bermuda Triangle between her legs—any man who dares venture near her voracious vagina vanishes without trace! After a catastrophic visit to the gynaecologist that sees her cooch claim another victim, the distraught Helen leaves for London, with concerned love-struck loser Dennis (Paul Conway) in hot pursuit.
Not content with Penetration Angst simply exploring the age-old vagina dentata myth, writer/director Wolfgang Büld also sees fit to add several equally bizarre subplots, including Dennis's awkward relationship with Siamese twin Sylvia (Amy Steel), and a pub stripper planning an armed robbery on the Isle of Wight; the result is a chaotic, darkly humorous film full of violence and nudity (with Horsey spending much of her time naked) that delivers messed-up madness by the bucket-load, but which tries a touch too hard to accommodate every twisted idea that Büld could come up with.
At 102 minutes long, the film ultimately outstays its welcome (it could do with being at least fifteen minutes shorter) but not before delivering such delightfully deranged moments as Dennis accidentally shagging Sylvia's sister and separating the girls with an electric bread-knife, a man pulled tongue first into Helen's insatiable snatch (which moans 'Feeed meee' just like Audrey II in The Little Shop of Horrors), a newlywed Helen being humped by her father-in-law (with inevitable results), and Dennis applying yogurt to his sun-burnt bell-end.
