Detective Nic Costa finds himself a stranger in a strange land when he's sent to infiltrate the mob in a remote part of southern Italy.
Roman police detective Nic Costa has been sent undercover to Italy's beautiful, remote Calabrian coast to bring in the head of the feared mob, the 'Ndrangheta
, who has offered to turn state witness for reasons of his own.
Hoping to reel in the biggest prize the state police have seen in years, the infamous Butcher of Palermo, Costa and his team are aware the stakes are high. But the constant deception is taking its toll. Out of their depth in a lawless part of Italy where they are the outcasts, not the men in the hills, with their shotguns and rough justice, the detectives find themselves pitched as much against one another as the mob. As the tension rises, it's clear the operation is not going to plan. Is Nic Costa getting too close to the enemy for comfort - and is there a traitor among them ...?
