The new documentary "Immutable" follows students in the Washington Urban Debate League over two years as they face challenges in their own lives and on the debate stage. In the program, students learn how to think critically, challenge their own opinions and find their voices through debate. Geoff Bennett spoke with the people connected to the film for a closer look.
