A man has been found dead at the foot of a seven-storey car park, suggesting he did not jump voluntarily. Martin and Anna go to find two witnesses, Bjorn and Bonnie. They go into some buildings separately, and suddenly Anna sees them. Bjorn points a gun at her, but she shoots him instantly. While Anna finds him dead, Bonnie runs away. The case is routinely investigated by the prosecutor and the travel team. Meanwhile, the detectives have trouble finding both Bonnie and Bjorn's gun. They manage to find Bonnie - dead of an overdose, but without a gun. Samira's father invites Kim with the family to Iran. He wants to come, but his mother's birthday is at the same time - and he has always celebrated it with her. Pressured by Karim, he gets his birthday moved up, but his mother doesn't give up so easily. She admits him to hospital in the hope that Kim will stay at home. Kim is not fooled, however, and instead promises her a postcard from Iran. Martin tries to support Anna, but when the travel team finds a video from a surveillance camera of Bonnie fleeing without a gun, Anna's explanation of self-defence crumbles and she is suspended and charged with killing Bjorn.
