Two of Sweden's most powerful businessmen have been murdered. In the face of mounting panic amongst the financial elite, a task force has been created to catch the culprit before he kills again. To his surprise, Detective Paul Hjelm, currently under investigation for misconduct after shooting a man who took a immigration office hostage, is summoned to join the team. But the killer has left no clues - even removing the bullets from the crime scenes - and Hjelm and his new teammates face a daunting challenge if they are to uncover the connection between the murdered men and identify any potential victims before he strikes again.
