The Girl from Cortina.

Vanessa Gravina is vapidly pretty as the heroine, who changes her hair color and hair style in order to escape an abusive painter husband and start a new life. She fakes her death by motorcar accident off a cliff, and the film heads downward from there, as surely as the vehicle plunges towards the Gothic waves-crashing-on-rocks below, set on the Greek island of Hydra.
