In the summer of 2011 a bomb goes off in the centre of Oslo, the capital city of Norway. The devastating explosion claims several lives, leaving hundreds suffering from various injuries. This attack was carried out by one man and as the capital struggled to deal with the aftermath of the bomb, little would they know that this same man would be on his way to carry out a massacre on an island just forty minutes away from the first attack in the city.
