Trapped in camps for years on end, many refugee stories largely go untold. On January 23, 2018, a new PBS FRONTLINE special, “Exodus: The Journey Continues” seeks to change that. “Exodus” tells the stories of refugees and offers a unique look at the global migration crisis by drawing on intimate footage filmed by refugee families themselves. One of the filmmakers, Hassan Akkan, began documenting his treacherous journey from Syria to Europe 2015.
