You don't have to be a president or a king to make a difference.

We Are the Ones (2015)

Directed by Jon Michael Shink

When tribal feuds ignite a firestorm of violence, three surgeons unite for peace. Francis grew up with little schooling during the Sudanese Civil War. Ajak is a Lost Boy who has returned to the tribe he fled as a child. Both men are proteges of Glenn, a grizzled, but brilliant American surgeon.
