Set in Austria in the early 1900s, Death Smiles on a Murderer stars Ewa Aulin, (Candy, Death Laid an Egg) as Greta, a beautiful young woman abused by her brother Franz (Luciano Rossi, Death Walks on High Heels, The Conformist) and left to die in childbirth by her illicit lover, the aristocrat Dr. von Ravensbrück (Giacomo Rossi Stuart, Kill, Baby... Kill!). Bereft with grief, Franz reanimates his dead sister using a formula engraved on an ancient Incan medallion. Greta then returns as an undead avenging angel, reaping revenge on the Ravensbrück family and her manically possessive brother.
