The House by the Cemetery (1981)

A young family moves from their cramped New York City apartment to a spacious new home in New England. But his is no ordinary house in the country: the previous owner was the deranged Dr. Freudstein, whose monstrous human experiments have left a legacy of bloody mayhem. Now, someone – or something – is alive in the basement, and home sweet home is about to become a horrific hell on earth.
