The Girl Who Knew Too Much

“LOOK... and you cannot look away for everywhere you turn it's there... watching... waiting to strike!”

Nora Davis (Letícia Román) arrives in Rome as a tourist who wants nothing more than a quiet holiday, until she watches a murder from a few feet away. The police don't believe her, since there is no body to show, and only Dr. Marcello Bassi (John Saxon) will listen as more killings follow. Mario Bava keeps the two of them circling a string of victims chosen in alphabetical order, each one drawing them closer together.
