Tania spent five years in prison without knowing anything about her sister. She returns to live with her sister, Danika, who is trying to help her to get up on her feet after she is released from prison. Tania is surprised that her sister Danika tells her about a long-term relationship via the Internet with a mysterious man she has not seen completely. Their lives are changing and Tanya is startled by this because she reveals that her sister's life is not so good.
Writer-director Tyler Perry throws all kinds of ideas at us, but he never manages to get over the basic problem at the center of his script: Sumpter's character is shallow and unlikeable, while Haddish's... wears out her welcome in record time.
You feel like you're the victim of a cruel bait-and-switch, lured into thinking Nobody's Fool would be a crappy but nevertheless entertaining Tiffany Haddish movie, only to have it turn out to be a crappy but nevertheless crappy Tyler Perry movie.
