Since 2011, millions of people have fled their homes in Syria and other countries besieged by violence, helping to fuel Europe's largest migration crisis since the end of Word War II. This two-hour special draws on camera and smartphone footage filmed by refugee and migrants themselves- inside sinking dinghies attempting to cross the Mediterranean Sea, in the trucks of human traffickers, and in the countries they hope to call home. Through its harrowing access and intimacy, Exodus vividly exposes a shadow-world of human traffickers exploiting the crisis for profit, how countries are handling the influx of people, and the challenges and choices these refugees and migrants face every day. Together, their stories paint an indelible portrait of this global crisis, and what it means to be a refugee.
