Friendship, courage and ingenuity are put to the test once again as Pertsa, Kilu and Pirkko embark on an epic adventure to solve the mystery of an old map. Twin girls Vappu and Kerttu also join the flight, and the suspense is increased when the cunning criminal Annabella Pehko jumps on board as a stowaway.

Helsinki in the summer is shown differently through the eyes of the homicide unit detectives, Timo Harjunpää and Onerva Nykänen; painting a picture of the city where people are not safe in the streets or not even in their own homes. In the midst of the hard crimes it is impossible not to feel the constant worry about your own family while being afraid of losing touch with your children.
