Cathy’s Curse (1976) [Blu-ray]

In 1947, a young girl is roasted alive in a car accident. Thirty years later, her grown brother returns to their childhood home with his mentally unstable wife and sweet daughter Cathy. But when the dead aunt's vengeful spirit possesses the child, it will unleash an unnerving nightmare of creepy mediums, demonic dolls, and plenty of sick 70s foul-mouthed moppet mayhem.
