“The house keeps us safe,” she says. “There’s nothing left for us outside.”

Esther is safe in the house. For sixteen years, she and her mother have lived off the grid, protected from the dangers of the outside world. For sixteen years, Esther has never seen another single soul.

Until today.

Today there’s a man outside the house. A man who knows Esther’s name, and who proves that her mother’s claims about the outside world are false. A man who is telling Esther that she’s been living a lie.

Is her mother keeping Esther safe – or keeping her prisoner?
