Al Sharpton shines a light on everyday people called to do extraordinary things--like Pauli Murray, who refused to give up her seat on a segregated bus months before Rosa Parks did the same, and Gwen Carr, whose private pain in losing her son Eric Garner stoked her public activism against police brutality. Sharpton also gives his personal take on more widely known individuals, revealing overlooked details, historical connections, and a perspective informed by years of working in the social justice movement.
