Puzzle

A man in London wakes with no memory and sets out to learn who he is. A stranger soon accuses him of betrayal, and the people who turn up around him, Sara Grimaldi (Senta Berger) and Edward (Luc Merenda) among them, seem to know more of his past than he does. Duccio Tessari follows him from one half-recognized face to the next, and each answer fits the last like a puzzle piece.
