It's 1962, a year after the death of Sam's father—he was a war hero—and Sam and her mother must move, along with their very liberal views, to Jackson, Mississippi, her father's conservative hometown. Needless to say, they don't quite fit in.

People like the McLemores fear that Sam, her mother, and her mother's artist friend, Perry, are in the South to "agitate" and to shake up the dividing lines between black and white and blur it all to grey. As racial injustices ensue—sit-ins and run-ins with secret white supremacists—Sam learns to focus with her camera lens to bring forth the social injustice out of the darkness and into the light.
