Syrian civil war escalates dramatically as the Islamic State gains more territory, purging cities and villages. Parisian Antoine Habert believes he recognizes 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.

Antoine joins a mission and is attacked by ISIS troops. The British Jihadists aren't all they seem.

Antoine, Sarya and the volunteers settle in a Kurdish village, and wait for Shamaran's battalion to arrive. The Kurdish village is spared, but the Jihads - under the 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.

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 realizes that Anna knew he was looking for her.

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.
