Hush Hush (1970)

Nora Grey is a straight-laced girl who always does the right thing. She has a level head and an independent streak that comes from raising herself for most of her life. She is very studious and has a firm, clear plan for the future -- but her entire life is turned upside down by the appearance of the new, attractive and darkly charismatic student at her school, a mysterious young man named Patch.
