Eleven Millimeter (S04E05)

When Caplan and Walter step in to apprehend "Baba" Aroudj in Marseilles, they inadvertently disrupt an ongoing investigation into a brutal robbery that took place a decade ago in Aubagne. Commander Guido Frankeur, who has been relentless in pursuing the case, plans to hold Caplan and Walter accountable for their meddling. However, he offers them a deal: assist him in dismantling the Turkish Mafia's operation, which is collaborating with the local Marseilles gangsters, or face the consequences of their interference.
