It's a roller coaste coming-of-age story. Focus is on the three kids thrown into extraordinary circumstances, which brings out best and worst in their relationship to themselves, each other, death and having to be/become an adult. Mum's corpse only appears briefly in the first episode, and the morbid aspects of the story are undertoned in relationship to the subtle humor.

Karla met Jonas during a summer vacation at the lake. After being unable to stop thinking about him and their kiss she phones him, making up a school assignment about children living in an orphanage, which is precisely where Jonas lives.

Karla invites Katrine to spend the holidays with her, hoping they might become best friends. As it turns out, nothing goes as planned. Karla meets Jonas and falls in love for the first time, and she nearly forgets all about Katrine. However, the two girls are forced to put their difficulties aside for a while, as they join Jonas in exposing a local gang of thieves.
