Three suburban youngsters are stuck at home in the care of their horrid, imperious Aunt Tess (Patricia McBride) while their father is out of town on business. Next thing you know, the youngest boy unintentionally kills Tess with a huge knife, and the siblings must find a way to dispose of her corpse. But before the trio can finish the job, their unhinged fugitive cousin shows up and puts a crimp in their plans in this 1988 cult classic.
