Every year, a growing number of people around the world leave their home countries in search of safety and a better life. The routes people take are often dangerous and uncertain, and stories of migrants going missing either during transit or once they reach their destination countries are widespread. For every missing person, there is a family left wondering whether their loved one survived the perilous journey.

The International Committee of the Red Cross and NBC Left Field teamed up with filmmaker Matthew Cassel to document the stories of five missing people from five different communities, across three different continents. These videos seek to piece together each missing person’s story through the words of loved ones left behind.
