Play Dead (1983)
A rich, elderly woman casts black magic spells on her vicious Rottweiler to murder her relatives.
Glamorous Yvonne De Carlo stars as Hester, a woman of wealth, and a woman of scorn... and the timid, be forewarned. With a maniacal hatred of her heirs, Hester has a thirst for revenge. Electrocution, strangulation, poisoning, and a crushed skull are just a few of her bloody tricks. Her beautiful niece is going nuts... and she's next on the list.
