Jabs (Miesha Tate) swore she would never throw a punch in the Valley again. Jabs now finds herself training Windsor to survive the painful, unexpected path she's about to take. Every corner. Every alley. Every doorway. She must follow the last footsteps of her sister in order to come face-to-face with Tory's killer in FIGHT VALLEY.
