Electrick Children (movie, 2012)

ELECTRICK CHILD tells the story of Rachel, a rambunctious girl from a polygamist colony in southern Utah. On Rachel’s 15th birthday, she finds a forbidden cassette tape. Having never seen anything like it before, Rachel plays the cassette tape, and finds glorious rock & roll thereupon. Weeks later, Rachel realizes a miracle has occurred - and the cassette tape must have something to do with it. She leaves her family and runs away to the closest city: Las Vegas. There she searches for the singer of the band on the cassette tape. She has a wild adventure and ultimately discovers who she really is: an ELECTRICK CHILD.
