Never Take Sweets from a Stranger(1960)

...and then he made us play that silly game...

Peter Carter, his wife Sally and their young daughter Jean move to a sleepy Canadian village, where Peter has been hired as a school principal. Their idyll is shattered when Jean becomes the victim of an elderly, and extremely powerful, paedophile. The film was neither a box office nor a critical success, it garnered criticism for breaking a significant public taboo.
