Although he’ll probably forever be best known, and perhaps rightfully so, for the radiation sickness outbreak epic Nightmare City (1980) and notorious cannibal classic Cannibal Ferox (1981), Umberto Lenzi doesn’t get nearly enough credit for the contributions to the giallo field. During the time period in-between Mario Bava’s jumpstarting the genre with The Girl Who Knew Too Much (1963) and Blood and Black Lace (1964) and Dario Argento’s opening the floodgates with The Bird With the Crystal Plumage (1970), Lenzi, along with many other filmmakers, was responsible for several thrillers that would continue to lay the foundations for where the giallo would eventually be headed in the 70’s. Long before the infamy of Salon Kitty (1975) and Caligula (1979), Eurotica maestro Tinto Brass delivered the Antonioni influenced pop art thriller Deadly Sweet (1967) which starrted Jean-Louis Trintignant and Ewa Aulin who would both go on to star in Giulio Questi’s bizarre and utterly singular Death Laid and Egg (1968). Even Lucio Fulci got in the giallo game early on with Perversion Story (1969). That same year also saw Lenzi began his string of erotic jet-set thrillers with the Carroll Baker led Paranoia (1969), So Sweet… So Perverse (1969) and A Quiet Place to Kill (1970) which Lenzi followed up with 1971’s Oasis of Fear, one of his best thrillers and a film which see’s Lenzi putting an interesting spin on previously explored obsessions.

After running into some trouble with the law in Italy they find themselves with a 24 deadline to leave the country and their luck gets even worse after being ripped off by a gang of bikers, leaving them with no money and no gas. The two eventually stumble upon a seemingly abandoned large estate and in a move of desperation, attempt to siphon gas from a car in the open garage, although they are interrupted by Barbara (Irene Papas), the lady of the house. After explaining their situation, Barbara becomes sympathetic and even invites them to stay and the three have a wild night together. The fun is short lived however as Dick and Ingrid discover Barbara’s reasoning behind keeping them around is far more sinister than what she originally led on.
