The police receive an anonymous call that tells of a murder. After identifying the victim, a long and demanding investigation begins, and only when a macabre mobile film is found do they come close to a solution.

In an act that can most be compared to a regular gangster murder, three people are found shot to death in a car outside Uddevalla. When you examine the victims' mobile traffic, you discover that they arranged a meeting with someone or a few at the scene. But the question of who or who they are, and whether they are also really the perpetrators, will not be easy to answer.
