Unable to come to terms with the tragic death of her husband, depressed mother-of-one Amelia is with her back to the wall. But life can become much bleaker. When the exhausted mum stumbles upon a mysterious pop-up children's book on a dusty shelf, vivid visions of a blood-chilling monster lurking in the bedroom's shadows start to haunt the nights of her troubled 6-year-old son, Samuel. With the boy's imagination becoming increasingly dark and graphic, Amelia, now concerned about Samuel's erratic behaviour, must take the time to listen. However, to confront the kid's horrible nightmares, she must first believe in the existence of a malevolent intruder living in a storybook. What if the boy is telling the truth? Can unconditional motherly love get rid of The Babadook?
