The Last House On The Left (1972) (UK-import)
US horror written and directed by Wes Craven. Easy-going Mari Collingwood (Sandra Cassell) and her fun-loving friend Phyllis (Lucy Grantham) are on their way to a Bloodlust concert to celebrate Mari's birthday when three escaped convicts kidnap and torture them. But Mari and Phyllis are fighters, and although they are drugged and beaten unconscious, stuffed into a car and driven into the woods for even more brutality, they are still alive - but for how long?
