Long Island, 1978. A young girl named Mary Mattock gruesomely murders her family with a hatchet and is locked away for life in Long Islands notorious Kings Park Psychiatric Centre. Ten years later Mary escapes from the asylum, leaving a grizzly wake of bodies and blood. Gunned down by the police, Mary meets her own demise outside the sanitarium walls. This incident gave birth to the legend of Mary Hatchets walking ghost and the mischievous night named in honour of her death, BLOOD NIGHT! A non-stop splatter fest filled with sex, guts and heads that roll!
