Madhouse

Julia (Trish Everly, in her only film role), a young teacher for deaf children living in Savannah, Georgia. Julia has horrid memories of her childhood, which was scarred by her sadistic twin sister Mary (Allison Biggers). At the urging of her uncle, Father James, Julia visits Mary, suffering from a severe skin disease, in a mental institution. The meet does not go well, and Mary vows to make Julia “suffer as she had suffered”. As their mutual birthday approaches, several of Julia’s friends and neighbors begin to die gruesome deaths, some of which committed by a mysterious Rottweiler dog that has some sort of connection to Mary. But is Mary really the killer?
