The Year Dolly Parton Was My Mom (2011)

It's 1976, and Elizabeth is just your average suburban 11-year-old praying for adolescence to arrive when she discovers that her whole life has been a lie. With only her imagination to guide her, Elizabeth runs away in search of her true identity. Her adoptive mother Marion is then forced to break out of the carefully-constructed "truth" to which she's been clinging, and go after her daughter. This leads to a cathartic cross-country trek by a mother searching for a daughter who's searching for a mother, both of them really searching for themselves. This movie is a poignant, sometimes funny, very female coming-of-age story that explores the tension between creating identity and finding it within.
