A Bay of Blood

With inheritance of a valuable piece of lakeside property at stake, several relatives set about severing family ties — permanently — in what is often cited as the original slasher flick (Friday the 13^th Part II stole several kills directly from this film). AKA Twitch of the Death Nerve, this is a true classic of Italian horror: smart, surprising and shot through with jet-black humour — and blood-red gore!
