It is the 1960s so of course just dumping barrels of radioactive waste in the sea just off beaches where people party is A-OK. Unfortunately one of these barrels springs a leak and creates a bizarre race of blood drinking monsters. The blood is first provided by Tina (Marilyn Clarke) who is having a swim after having a tiff with her boyfriend at a beach party where much rock and roll is played. The attacks soon escalate though including a twenty teen girl slumber party which is wiped out by these monsters.
Luckily Dr Gavin (Allan Laurel) has a solution: sodium! As Hank (John Lyon) heads to NY to buy supplies of sodium, his girlfriend (Alice Lyon) is in peril from the monsters at a quarry...
So, this is fairly generic and low budget. The monsters are ridiculous of course but that adds to the film's camp charm. It is rubbish, but fun rubbish and that makes it very watchable.
