The story of Peter Rätz, Sweden's most well-known and successful police infiltrator of all time. For nine years, Rätz entered deep into some of Sweden's most dangerous criminal gangs and now lives hidden in an unknown place.

A wheel loader drives straight through the metal gates at the Akalla security deposit box. Five minutes later, three armed masked robbers leave the site with just over SEK 26 million in cash. Already the next day, the police are the robbers on the tracks.

On December 4, 1994, one of the worst mass murders in Swedish criminal history occurs. Guests are on their way home when it is suddenly shot with an automatic weapon straight into the entrance of the nightclub Sturecompagniet in central Stockholm.

The night of Saturday, August 8, 1992, the alarm goes off at Gotabanken in Alby. A security guard goes to the scene but finds no suspect. When the bank staff unlocks the vault on Monday morning, they are met by boreholes in the ceiling and leaking water pipes.

During the 1980s, Sweden is shaken by a series of violent explosive attacks directed at the authorities and the judiciary, an act that is unparalleled in Swedish criminal history. It will be a fight against the clock to try to reach a solution before the next bombing happens.

In the early 00s, the novelist Ulf Borgström spreads terror in southern Sweden. The number of wildfires is steadily increasing and a pattern will soon emerge. For several years, the man now known as Gryningspyromanen is running a fiery crusade against society.

Two days before Christmas Eve 2000, three armed robbers strike the National Museum in Stockholm. In just a few minutes, art is stolen by Rembrandt and Renoir for a value of over SEK 300 million, after which the perpetrators disappear from the scene in a motor boat.

Late at night one day in June 2003, a transport of value rolls into the small Blekinge community Bräkne-Hoby. The robbery initially goes according to plan, but gets an abrupt end when heavily armed police from Malmö arrive.
