The true story of a day that started like any other
Anders Behring Breivik dresses in a police uniform, loads a van with home-made explosives, and drives to Regjeringskvartalet, the executive government quarter in Oslo, Norway. He leaves the van outside the office of Prime Minister Jens Stoltenberg. Moments later, it explodes, causing several casualties.
On the island of Utøya in Tyrifjorden, Buskerud, teenagers have arrived for Workers’ Youth League (AUF) summer camp, organised by the ruling Labour Party. When they learn of the bombing, one student, Viljar Hanssen, calls his parents to make sure they are unhurt.
Breivik arrives at the ferry landing and tells staff he is a police officer sent to secure the island following the attack. The camp director transport him to the island by boat. Breivik instructs the staff to gather the children in one location. When the head of security asks for ID, Breivik shoots him and the director dead. The children flee as Breivik opens fire, murdering dozens.
Viljar and his brother Torje hide on a rocky embankment on the beach. Viljar calls his mother to tell him a shooting is in progress. Breivik finds the group and starts shooting. Viljar is shot multiple times, but Torje escapes unharmed. Breivik surrenders to a tactical team and is brought inland for interrogation.
Breivik claims he is the leader of a white nationalist group called the Knights Templar and that more attacks will happen on his signal. He requests the aid of lawyer Geir Lippestad, who defended a Neo-Nazi. Lippestad is morally conscientious of his client and professionally bonded by his ethics as a lawyer. Lippestad tries to argue an insanity defense for Breivik, which draws criticism as it means he will be institutionalized instead of imprisoned. With the help of various psychiatrists and psychologists, Breivik is possibly diagnosed with paranoid schizophrenia. Breivik tells Lippestad he wants to be declared competent to legitimize his attacks.
Viljar wakes from a coma with life-changing injuries and returns home with his family. He learns to walk again, but is haunted by memories of the attack. With the support of his mother, and another survivor of the attack on Utøya, he appears in court as a witness and delivers an account of the massacre. Breivik is sentenced to indefinite solitary confinement.
