One of Rollin's early, cruder efforts, this weird and sometimes wonderful film mixes bizarre fashions, clumsy action, beautiful locations, dream images, casual eroticism and, unusually, a strangely humane finale.
An obsessed industrialist tries to discover the secret of immortality by kidnapping and experimenting on a vampire girl, while her kind consequently stage a rescue which inverts the usual horror film finish as staid, torch-bearing vampire mutants quietly storm the humans' castle. Absurdly plotted, this is still somehow rather impressive, with a novel premise and leaving you somehow rooting for the vampires, no mean feat.
