A single mother working in the gothic mansion of a reclusive horror director stumbles upon terrifying secrets.

Harry Adams loves horror movies, so it’s no coincidence that she accepted a job cleaning house for horror-movie director Javier Castillo. His forbidding gray-stone Chicago mansion, Bright Horses, is filled from top to bottom with terrifying props and costumes as well as glittering awards from his career making movies that thrilled audiences—until family tragedy and scandal forced him to vanish from the industry.

Javier values discretion, and Harry always tries to keep the house immaculate, her head down, and her job safe. Then she hears noises from behind a locked door, noises that sound remarkably like a human voice calling for help. Harry knows not asking questions is a vital part of keeping her job, but she soon discovers that the house may be home to secrets she can’t ignore.
