The premise
A tourist witnesses a murder and finds herself caught up in a series of bloody killings.
Horror Vault's take
Set against the shadowy streets of Rome, this early Mario Bava thriller follows an American tourist whose nightmare begins the moment she witnesses something she was never meant to see. Dismissed and disoriented, she finds herself drawn deeper into a web of connected killings that may stretch back years. Bava crafts a sleek, black-and-white atmosphere dripping with dread, blending whodunit mystery with genuine menace. Often cited as a foundational text of the giallo genre, it's a landmark work of Italian horror cinema.
