La sorella di Ursula (1978)

In the wake of their father’s death, two beautiful sisters – sensitive Ursula (Barbara Magnolfi of Suspiria) and promiscuous Dagmar (Stefania D’Amario of Zombie) – come to a seaside resort for a relaxing vacation. But their idyllic getaway will soon become a depraved nightmare of kinky exhibitionists, dope-sick lotharios, lust-crazed lesbians and a psychotic killer who tears women to pieces with – no kidding – a phallus of massive proportion. Marc Porel (The Psychic) co-stars in this eye-popping combination of delectable sexploitation and vicious giallo.
