What You Do Not Know

he late-summer warmth lingers on Gotland. Maria Wern is at a party with her new neighbors in Åminne when an explosive fire breaks out in a nearby house. The incident is linked to a series of burglaries in the summer cottage area.

The following morning, Tomas Hartman's daughter, Sofi, vanishes without a trace from the beach in Åminne. On behalf of Region Gotland, she had been investigating the consequences of oil drilling on the island. Her disappearance occurs the day before the results are to be presented. Both environmental activists and venture capitalists in the oil industry are eagerly awaiting her findings. The protests against oil drilling are led by Rasmus Flöjel, Sofi's boyfriend during high school. More and more people are joining the demonstration.

Tomas Hartman fights a desperate race against time to find his daughter. He knows how anxious and vulnerable she truly is, and how hard she must struggle against her own demons.
