A woman and a man in their forties meet up for the first time IRL in a municipal gymnasium with the intention of creating a space of trust between themselves. A ”room” where they safely can explore sides of themselves that they suppress in their everyday lives.

Shortly after police discovers the murder of three friends, police inspector Wallander finds his friend and colleague Svedberg dead. First, it is believed that Svedberg killed himself but Wallander soon discovers links between Svedberg, the three friends and a fourth person, a young woman in a mental hospital.
