2014, the Syrian civil war escalates dramatically as the Islamic State gains more territory, purging cities and villages. In news footage, Parisian Antoine Habert believes he recognises his dead sister and flies to Turkey to learn more about the woman in the video.

Antoine is interrogated by a YPJ officer and treated as an ISIS prisoner. The arrival of three British jihadists dramatically changes the balance of power between ISIS and the Kurds. With the help of the three Brits, the Kurdish base is attacked by mortars.

Antoine joins Sarya's commando force on a mission to blow up the bridge. Mission completed, they are ordered to join Shamaran's unit. In the ISIS village, the British Jihadists get used to their new life and take part in violent actions against civilians.

Antoine, Sarya and the volunteers settle in a Kurdish village, and wait for Shamaran's battalion to arrive. At night, the offensive begins. The Kurdish village is spared, but the Jihadis - under Nasser's command - defeat the Kurdish female fighters in the frontline.

After accepting that Anna is dead, Antoine decides to leave Syria and go back home. However, the entire region was taken by ISIS. Sarya is tasked to escort Antoine back to the Kurdish capital. Distraught by the atrocities he has seen, Nasser asks Stanley for a way out.

This episode explores Anna's story chronologically, from the moment she left Paris.

After killing a man and saving Sarya's life, Antoine cannot leave Syria and volunteers to fight alongside the Kurds. Anna arrives to base and Antoine realises that Anna knew he was looking for her. Anna assembles a strike force to assassinate a high-rank ISIS commander.

ISIS reinforcements are pouring to the area of the assassination, forcing Anna to run. Nasser is evacuated to ISIS HQ but Paul discovers his betrayal. At a secure location, Stanley introduces Nasser to his new handler: Anna. Antoine and injured Sarya return to Paris.
