Mallory Quinn leaves the rehabilitation center and gets a job as a nanny for the Maxwell family. She is satisfied with her work, finally regains her physical form and achieves stability in life. The girl has to take care of the shy five-year-old boy Teddy. He always carries pencils and a drawing album with him, where he depicts trees, rabbits, balloons. But one day a creepy plot appears in the boy's album. A dark forest and a man dragging a dead woman's body. Teddy's drawings become more and more ominous. Where could a five-year-old child see such bloody pictures? Mallory guesses that the boy has witnessed something terrible. All this amounts to some kind of madness. What the girl will see in the next picture of Teddy will make her choke on a silent scream...
