The series follows the events during the fall and winter of 1991–92, when John Ausonius shot a total of eleven people with an immigrant background. The series partly follows Ausonius during the execution of the crime, and partly the police's detective work. The series also provides an insight into Ausonius' earlier life, from high school age onwards.
