Arnaldur, a 16-year-old boy living a normal teenager's life in Reykjavik. One day, coming home from school, he finds his brother in the bathtub, dead. Despite clear signs of a suicide, Arnaldur is convinced that his brother's teacher is somehow responsible so he decides to take matters into his own hands and avenge his brother.

In the mid to late '90s, the Reykjavik crime and drug scene saw a drastic change from a relatively small and innocent world into a much more aggressive and violent one.. The film tells the story of this change through the fictional gang of pushers that took control of Iceland's underworld.
