David, a high-ranking GIGN officer, is preparing to leave field operations. But a new recruit's graduation and a shocking attack threaten his plans.

Devastated by the previous night's events and under new scrutiny, the squad tracks down a suspect. On a mission, Max disobeys a direct order from David.

After the forest shootout, David pockets key evidence. Max continues to question his father's passing, and a hospital visit takes an ominous turn.

Having linked the mastermind behind the attacks to an old operation, David goes on a rogue mission - but he's not the only one searching for answers.

David faces the consequences of his actions. Brought in for questioning, he tries to protect Max, and finally tells his godson the whole truth.

As news of a hostage situation reaches the squad, they race to launch a rescue mission and take down a skilled assassin who has nothing left to lose.
