The 'Ndrangheta is a ruthless mafia organisation, one of the richest and most powerful organised crime groups in the world. Completely impenetrable to outsiders, merciless when crossed, they run the savage Calabrian coast of Italy, their influence everywhere. So why has the head of this feared mob, Lo Spettro, offered to turn state witness?
Detective Nic Costa is sent deep into the mountains to infiltrate this mafia family, with Lo Spettro's help. With a new identity, Nic becomes one of their own. But one slip up would mean the end not just for the investigation, but for Nic, and his whole team.
