Mallory is delighted to have a new job looking after gorgeous five-year-old, Teddy. She's been sober for a year and a half and she's sure her new nannying role in the affluent suburbs will help keep her on the straight and narrow.

That is until Teddy starts to draw disturbing pictures of his imaginary friend, Anya. It is quite clear to Mallory and to Teddy's parents, even in his crude childlike style, that the woman Teddy is drawing in his pictures is dead.

Teddy's crayons are confiscated, and his paper locked away. But the drawings somehow keep coming, telling a frightening story of a woman murdered... and they're getting more sophisticated. But if Teddy isn't drawing the pictures anymore, who is? And what are they trying to tell Mallory about her new home?
