This is a powerful and gritty story, based on the true events of an unemployed single mother who spends more than two decades working tirelessly to exonerate her wrongly convicted brother.

Betty Ann Waters (Hilary Swank) is convinced that her brother Kenny (Sam Rockwell) is innocent of the murder he was put away for.

So, vowing to clear his name, she puts herself through law school whilst working as a waitress and raising two sons.

A raw and powerful tale, with some incredibly strong yet subtle performances from Swank and Rockwell. It will take you through whirlwind of emotions.
