Rachel is 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.
