In a quiet little town in northern France, an improbable sequence of events takes place which will go on to transform completely the struggle against organised crime in Europe. It all starts when the French cybercrime police hacks into an encrypted service called Encrochat: suddenly anonymity crumbles and murder contracts and drug deals become visible on the screen. Police are able to follow communications between drug couriers, gang leaders, and teenage hitmen in real time.

To save lives, the police must respond quickly, but must also be careful not to reveal that they're listening in. As unexpected arrests of criminals grow increasingly frequent, criminal networks come into view, with nodes dotted all across Europe, all prepared to do whatever it takes to gain control of the drug trade. One name in particular will come to haunt the investigators: the Kurdish Fox, a notorious gang leader with ambitions to become the Pablo Escobar of Scandinavia.
