Double bill of 'giallo' thrillers from Italian director Luciano Ercoli. In 'Death Walks On High Heels' (1971) Susan Scott stars as Nicole, the daughter of a murdered jewel thief. When nightclub dancer Nicole is questioned by police in Paris as to the whereabouts of some diamonds suspected to have been stolen by her father, she is unable to give them any information. Shortly after, Nicole is stalked by a balaclava-wearing man with distinctive blue eyes who is certain she knows more about the diamonds than she is letting on. A terrified Nicole flees to England but soon finds her life in peril once again... Scott also stars in 'Death Walks at Midnight' (1972) as model Valentina, who agrees to take LSD with her journalist boyfriend Gio (Simon Andreu) to explore its effects. Shortly after taking the drug, Valentina believes she sees a woman being murdered with a brutal weapon. Convinced that the murder really took place, Valentina discovers that an identical murder was committed only months before. Shunned by the police, she decides to investigate the mystery for herself but what she unearths puts her life in grave danger.
