A fishing cutter collides with a small motorboat in the open sea off the small island of Farö. The Nyman couple died, the Brolin fishing family survived. In the first questioning, father Janne and son Andreas stated that it was an accident. They tried to stop the Nymans from illegally shooting a seal. But they do not say who was steering the cutter at the time of the accident. When Commissioner Anders and his colleague Karin bring the couple's daughter, Agnes Nyman, the news of the death of their parents, she doubts the Brolins' testimony.
