This is a story of Ida and Krister. It's about a relationship that goes to hell. They are both crazy in love but manage to strangle the supply of oxygen and adapt to each other in a way that will lead to catastrophic consequences.

In central Gothenburg, Sweden, a group of boys, aged 12-14, robbed other children on about 40 occasions between 2006 and 2008. The thieves used an elaborate scheme called the 'little brother number' or 'brother trick', involving advanced role-play and gang rhetoric rather than physical violence.
