A canine trained to kill provides the gruesome action in this horror film. Hester Yvonne DeCarlo buys a rottweiler by the name of Greta and then gives it to her niece Audrey (Stephanie Dunnam) with completely malicious intent. Hester has always hated her sister (Audrey's mother) for marrying the man that Hester loved. Now that both of them are dead, Hester wants revenge on Audrey and her family and friends. She controls Greta's killer activities through a series of hocus-pocus incantations. A dim-witted police inspector is not much of a threat to Hester or her murderous canine who are getting away with murder, at least for awhile.
