"It's about a picture perfect family that crumbles when the father is killed in a car accident. You learn that the mother ran away from her extremely wealthy family in order to marry him but, when he dies, she can't handle having to take care of herself, so she crawls back to her parents and claims she has no children.
They accept her back and, while their mother lives her best life, her four kids are left in a hotel. When they come find her because they're starving, she locks them in the attic of her parents' house. Neglect, malnourishment, incest, poisoning, and more...it's just messed up."
