Mamma, Pappa, Barn

Three year-old Hanna wakes up completely alone in a locked flat. She knows that her daddy is in Japan – but where is her mummy? Could it be that she has moved out, leaving Hanna behind?
The following morning, Petra Westman from the Hammarby Police finds an unconscious infant in some shrubbery, and shortly thereafter stumbles upon the mother’s dead body hidden inside a gritbin. The strange thing is that nobody seems to be missing them.
But just as an investigation is launched, the Hammarby Police is faced with yet another case. A teenage girl has been found murdered onboard Cinderella – one of Viking Line’s cruiseships – and during a visit to her family home, it soon becomes clear that her younger sister is likely to meet a similar fate.
Both cases turn out to be difficult challenges for detective chief inspector Conny Sjöberg and his colleagues, especially as the team itself is afflicted with internal troubles and personal tragedies.
