Gorgonas (2004)

It is the modern times. In an unknown city humans are dead, petrified on the spot. A young man and woman enter the Faculty of Law to find and destroy the monsters that are creating such a havoc. The girl informs the guy that the monsters are not others that the three sisters of the former pop-group Elektra, and tells him their story of of how they've become gorgons. They know the Greek myth and what to do when facing them, but will that be enough to destroy the horrific and destructive triplets?
