Tony Kendall stars as the man hired to protect a girls boarding school from the Lorelei, a mythical creature that appears, tears up its victims and eats their hearts! The head of the school played by the beautiful Silvia Tortosa distrusts Kendall at first and doesn't like him near the girls.
He falls for another woman who it turns out transforms into the Lorelei, even though he loves her he knows he must put a stop to the carnage.
Though not as good as Tombs of the Blind Dead this is a worthy film from De Ossorio and some of the killings are quite graphic (you get to see chests ripped open and hearts torn out!) and there are some really nice atmospheric moments, the film is let down slightly by the creature itself which is really quite laughable but at the end of the day it probably adds to the fun.
