Molly is a paleobotanist who spends her days working at a fossil quarry where she sometimes unearths artefacts that defy understanding, including a controversial Bible that has recently attracted gawkers and conspiracy theorists. By night, she cares for her two young children - four-year-old Viv and one-year-old Ben - while her musician husband is away on tour. She’s frazzled, sleep-deprived and it seems the edges of her reality blur more each day.

When she hears an intruder in the house, Molly is desperate to keep her children safe. She confronts the figure in the deer mask - and discovers that this stranger knows everything about Molly and her family. Molly fears the most sinister motives even as she reluctantly, terrifyingly, acquiesces to the intruder’s demands. What happens once she learns the true identity of the trespasser is chilling and otherworldly.
