The Blind Dead Series (Part 2) "Return of the Evil Dead" (1973)

Released the year I was born.
Part 2 of 4 of the classic Spanish-made horror series.
500 years after they were blinded and executed for committing human sacrifices, a band of Templar knights returns from the grave to terrorize a rural Portuguese village during it's centennial celebration. Being blind, the Templars find their victims through sound, usually the screams of their victims. Taking refuge in a deserted cathedral, a small group of people must find a way to escape from the creatures.
Sorry, no Ash hero with a chainsaw-hand in this one.
