Season 2

Targeted by an enemy who has sworn to eliminate them, Vincent and Alban now live under false identities in the Moroccan desert. But when Alban learns that his mother is seriously ill, Vincent, who dreams of seeing Louise again, convinces him that it's time to flee and finally return to Beaucastel. They strike a deal with a crook to obtain false papers.

In a Moroccan prison, Vincent and Alban are threatened with death if they don't carry out a dangerous mission: find out where one of their fellow inmates, Attila, a bloodthirsty psychopath, has hidden a shipment of drugs. With Christmas approaching and their hearts set on returning home to their loved ones, the situation seems hopeless.

Following a misunderstanding, Vincent and Alban are mistaken for scientists who are experts in biological weapons and find themselves members of a mercenary commando unit searching for VX, a formidable biological weapon that they must steal from a high-security laboratory in Scotland.

It's the final stretch for Vincent and Alban, who are determined to return home but are still carrying a dangerous vial. Vincent uses it as a bargaining chip to negotiate with the DGSE to get their old lives back. But in Beaucastel, in the middle of the Christmas market, all their enemies converge, ready to do anything to neutralize them once and for all.
