Five friends visiting their grandfather's house in the country are hunted and terrorized by a chainsaw wielding killer and his family of grave-robbing cannibals.
Relentlessly effective horror shocker that stops at nothing in its terror - with grim humour (if you can take it) and all filmed in broad daylight.
Halliwell**: "Relentless horror thriller adapted from real events which also inspired Psycho; its cult success led to a flood of similar slasher movies, though few reached its level of sustained terror."
Maltin***: "Sweat-inducing, claustrophobic, unrelenting suspense-comic-horror film. Classic and influential - and nowhere nearly as violent as it's reputed to be."
