An alarm sounds in the middle of the night for a burglary in progress at a winter-closed campsite in Bredäng, outside Stockholm.

The police spot a light in one of the farthest caravans and when the officers open the door they are greeted by a horrific sight. Floors, walls and furniture are completely covered in blood. A man has been killed with an axe and brutally dismembered.

On the floor lies a young man sleeping with a severed arm as a pillow. He is arrested and taken to Kronoberg prison, identified as seventeen-year-old Hugo Sand, the son of a famous writer.

Hugo suffers from a rare sleepwalking condition that is activated by nightmares. He is either the perpetrator or a witness, but claims to remember nothing from the night.
