Trapped inside a brutal, isolated cult village, a brave nine-year-old girl has only ever known her mother as a heavily chained captive called "Wretch." Everything changes when she uncovers a torn photograph revealing her mother's true identity: Grace Miller, a once-famous champion runner. Realizing that her mother is their only hope for survival, the little girl makes a devastating sacrifice: she unlocks her mother's heavy chains and stays behind to face the cult's brutal punishment, begging Grace to run as fast as she can to find help.
