Whistle: A Terrifying Supernatural Chiller About a Mysterious Train Set and a Mother's Nightmare

Annie Blunt has endured a devastating year: her husband died in a hit-and-run accident, and a scandal involving one of her children's books damaged her writing and illustrating career. Seeking recovery, she and her young son Charlie move to a small town in upstate New York. In their new home, Charlie discovers a forgotten train set in a locked shed on their property. While Annie is relieved to see him engaged, she becomes disturbed by the toy. Strange sounds—resembling a train whistle—wake her at night despite no active railroad nearby. Unsettling events begin occurring in the neighborhood, and Annie finds herself compulsively drawing a disturbing character unsuitable for children's books. As psychological disturbances intensify, Annie struggles to distinguish between grief-induced delusion and genuine supernatural threat. What began as a search for healing becomes a descent into a new nightmare.
