In 1974, single mother Doris Bither reported being violently assaulted by an unseen force inside her Culver City home. As the attacks escalated, investigators from UCLA documented a series of terrifying events that would become one of the most infamous paranormal cases in American history. Based on the true story that inspired The Entity, WHAT HAPPENED TO DORIS? tells the story through the eyes of the family who lived it. Starring Heather Graham, WHAT HAPPENED TO DORIS? is a harrowing supernatural horror film about an unimaginable haunting—and the devastating cost of refusing to believe its victim.
