Struggling but unapologetically living on her own terms, Inez is moving from shelter to shelter in mid-1990s New York City. With her 6-year-old son Terry in foster care and unable to leave him again, she kidnaps him so they can build their life together. As the years go by, their family grows and Terry becomes a smart yet quiet teenager, but the secret that has defined their lives threatens to destroy the home they have so improbably built.

Armed with a clear vision, Richard Williams guides his extraordinarily talented daughters, Venus and Serena, on their journey to tennis superstardom.
