Inspired by the mythology of the International Brigades of the Spanish Civil War, over 300 foreign volunteers chose to give up their comfortable lives and go fight ISIS in Raqqa. We filmed them there, fly-on-the-wall style, fighting, talking, laughing, being attacked by suicide bombs and sniper fire. We were with them until Raqqa was freed. And then we followed them back home – changed forever.

Some of them went back home. We were there when they told their story to their families. This is the untold story of the young Westerners who left everything behind to fight ISIS.
