Pregnant by her own father for the second time, 16-year-old Claireece ''Precious'' Jones (Gabourey ''Gabby'' Sidibe) can neither read nor write and suffers constant abuse at the hands of her vicious mother (Mo'Nique ). Precious instinctively sees a chance to turn her life around when she is offered the opportunity to transfer to an alternative school. Under the patient, firm guidance of her new teacher, Ms. Rain (Paula Patton), Precious begins the journey from oppression to self-determination.
