Coal Miner's Daughter (1980)

At only 13, Loretta Webb marries Oliver "Doolittle" Lynn and is soon responsible for a large family. She appears destined to a life of homemaking, but Doolittle recognizes her musical talent, and buys her a guitar as an anniversary present one year. At 18, the busy mother of four children still finds time to write and sing songs at small fairs and local honky tonks. This gift sets Loretta Lynn on the grueling, tumultuous path to superstardom and country music greatness.
