Stop me if you've heard this one: Some teens head to the woods to party, take a dip in the lake, have wild sex, and are subsequently hunted down and killed by a machete-welding maniac. Sound familiar? Well, it should - it's only the plot of every "Dead kids in the woods" movie since Madman and Friday the 13th.
It's also one of the bloody set pieces in Mario Bava's classic Italian giallo/horror film "Bay of Blood", AKA "Twitch of the Death Nerve". Almost a full decade before the the 80s slasher films exploded with tits and gore, Bava was inventing the tropes that would bring the horror genre the most attention it had received - both wanted and unwanted - since the Universal Horror Monsters took center stage.
