From IMDB:

A mysterious blonde woman kills one of a psychiatrist’s patients, and then goes after the high-class call girl who witnessed the murder.

From Kanopy or Amazon Prime you can stream this 43 year old film starring Michael Caine and Angie Dickinson.

While watching this vintage film, I was struck by how young the actors were,  how sexually daring this film must have seemed way back then, how acting has changed, and what a good story and plot shock the film still provides.

Give this piece of film history a try.
