Amelia is a young woman whose life is enveloped in tragedy. Seven years ago, her husband died while driving her to the hospital to give birth to their son Samuel. Raising a child alone has meant a lot of stress and sleepless nights. Samuel has always been a handful behavior-wise, but things get even worse when one night he and Amelia find a peculiar book to read for bedtime, The Babadook, about a darkly mysterious figure whose malicious intents directed toward this mother and child are made clear in the nursery rhyme text.
What is this thing? What does it want? And how did that book get in the house? Amelia must figure it all out and do something about it before it’s too late.
