Indoor soccer is what Lizzie does best. At school other kids bug her and her teacher thinks she's a troublemaker, but during a game she feels focused, free.
Lately, however, her younger sister Shelby has taken up the game. Shelby's a nice kid, but she leads a charmed life--she copies everything Lizzie does, then does it better. Soon Shelby is a soccer star and her team is challenging Lizzie's in tournament play. When the girls are pitted against each other on the field, hurt feelings fuel a brutal competition, with dangerous results.
Off the Wall shows the difficulty of acknowledging the best qualities in those we love, and in ourselves.
