"Precious" Jones (Gabourey "Gabby" Sidibe) is a high-school girl with nothing working in her favor. She is pregnant with her father's child - for the second time. She can't read or write, and her schoolmates tease her for being fat. Her home life is a horror, ruled by a mother (Mo'N****) who keeps her imprisoned both emotionally and physically. Precious's instincts tell her one thing: if she's ever going to break from the chains of ignorance, she will have to dig deeply into her own resources.
