Oskar is a lonely boy from a broken home. He's bullied at school and is longing for friendship. Eli is a troubled girl who's just moved in next door. She never goes to school and is compelled to fill an eternal emptiness. When a series of brutal killings plagues the neighbourhood, these two young misfits make a deep connection, sensing in each other a kindred spirit. But the shocking truth about Eli tests Oskar's loyalty - and love - beyond all imaginable limits.
