On the outside it looks like Suzette has it all. A stunning ultra-modern home, designed by her handsome Swedish husband. A beautiful, but silent, seven-year-old daughter who is fiercely intelligent. But under the shiny veneer, the cracks are all too clear.

For her daughter Hanna isn’t just clever, she’s dangerous. Her behaviour is carefully calculated. She adores her father, yet wants Suzette to disappear. And as Hanna’s tricks become increasingly sophisticated - from tampering with her mother’s daily medication, imitating a rabid dog, to setting Suzette on fire - it’s increasingly clear that there is something seriously wrong with their little girl.

Because what kind of child wants to kill their own mother?
