Celie is a young poor, uneducated 14-year-old African-American teenager girl living in the Southern United States in the early 1900s. She writes letters to God because her father, Alphonso, beats and rapes her. Alphonso has already impregnated Celie once, which resulted in the birth of a girl, Olivia, whom Alphonso abducted. Celie believes that Alphonso killed Olivia. Celie then has a second child, and Celie's ailing mother dies after cursing Celie on her deathbed. The second child is a boy named Adam, whom Alphonso takes from Celie shortly after his birth.

Celie and her younger sister, 12-year-old Nettie, learn that a man identified only as "Mister" wants to marry Nettie. Alphonso refuses to let Nettie marry, instead arranging for Mister to marry Celie. Mister, a widower, needing someone to care for his own two children and keep his own house clean, eventually accepts the offer. Mister physically, sexually, and verbally abuses Celie, and his two children mistreat her as well.
