When normal people think crime, they mean murder, kidnappings, drug dealing and the like. But police professionals consider this merely to be the "Third Division." The first league of crime is much more dangerous, deadly, and almost impossible to fight. In the seemingly well-ordered and peaceful city of Göteborg in Sweden, a special ops unit, called SSI, is put together to fight the truly dangerous criminals: former secret service agents, KGB assassins and their ilk which are involved in all aspects of international organized crime.
They're the ones the SSI is willing to go much, much further than any other police unit to combat. Johan Falk is asked to join the team since he's considered loyal, uncompromising and fearless. But Johan now has a life partner and children; can he still be as morally steadfast as before? And when he learns about the unit's covert mission – using non-police related, private citizens to infiltrate major Eastern European crime syndicates – Johan begins to ask himself where fighting crime ends and fostering crime begins… A completely new type of crime series set in a world of moral ambiguity, inspired by authentic cases, and vibrant with tension and suspense!
