Spending her holidays on the Swiss/Italian border, Margareta (Lina Romay) meets charming Sandra Mauro (Monica Swinn) and her husband. She agrees to stay in their house for the rest of her vacation, unaware that they are going to use her for smuggling diamonds over the border. There they get a little 'deeper' into knowing each other, but one night she awakens to strange noises and finds the couple brutally murdered in their living room. Margareta, deeply traumatized and unable to speak, is taken to Dr. Antonio's asylum. Antonio tries his very best to get her to speak and to reveal the events of the dreadful night. His attempts are not unselfish, since every member of the medical staff has already tried to be the first to find out where the missing diamonds are hidden. One night a mysterious black robbed person kills one of the nurses. Is this just a random attack or has somebody tried to get rid of a possible competitor. Only Margareta, who saw the killer, is able to uncover the mystery…

Set in an unspecified French village, the locals are shocked when a group of girls skinny dipping in the nearby lake (all very tastefully done I hasten to add) are killed by a group of zombiefied Nazi soldiers, that spring up out of the waters and drag them down to their demise.
A couple of detectives are brought in to try and solve the mysterious murders, only to end up as the zombies next victims. It turns out that during the war, the French resistance ambushed and killed a squad of German soldiers and dumped the bodies into the nearby lake, but failed to take notice of any of the local superstitions (never a wise move). Although, seeing as this film appears to be set in the early 80's, why it's taken so long for them to emerge and start killing people is a bit of a mystery, but there you go.
Not-with-standing, the villagers quickly organise a lynch mob to take down the zombie menace, only to end up being decimated by the undead soldiers, who's 'convincing' zombie make-up basically consists of green paint, which doesn't even cover the whole of the actors faces and keeps washing off in the lake.
There's also a bizarre sub plot about one of the zombies visiting his former daughter, who strangely still looks all of 12 despite the fact she should be in her 40's if she was born near the end of the war, but then since when did logic ever come into these films? Such as why do their uniforms still look almost new despite being underwater for 40 years, or how come the skinny dipping girls are only knee deep in the water when viewed from the lakeside, yet appear to be swimming in 12 feet of it from the underwater shots?
Bad acting, naff zombie make-up (the aforementioned green face paint), painfully obvious underwater shots filmed in a swimming pool, not to mention the plot inconsistencies bigger than the aforementioned lake itself. Low budget doesn't even begin to describe this film, which quite unbelievably was directed by respected Eurohorror director Jean Rollin, albeit under the pseudo name J A Laser.
That's not to say the film isn't without merit. I bust a gut laughing at the thoroughly ridiculous scenes of the zombies attacking the naked young girls, and the equally ridiculous slapstick battle with the angry villagers. Utterly hilarious, grab the six pack and the popcorn and have a blast!
