Based on the remarkable true story of working-class hero Lilly Ledbetter (Patricia Clarkson), a hard-working Alabama tire factory supervisor struggling to lift her family into the middle class. Having grown up in poverty, she endures a work environment plagued by pervasive harassment for the sake of the best paycheck in the county.

As retirement approaches, Lilly discovers that her employer has been paying her half of what the men with the same jobs are earning. Outraged, Lilly fights this injustice in the halls of Congress, the Supreme Court, and eventually, The White House - all while powerful forces try to shut her down.

Directed by Rachel Feldman and co-starring John Benjamin Hickey and Thomas Sadoski, Lilly follows the transformation of an ordinary citizen into the face of an issue, illuminating the impact a single, courageous person can have.
