Beth has always had a dream to live in the 1970's, the decade of peace, love, and happiness, not to mention the legendary decade for rock n' roll bands. She's always been different from everyone else and her music taste prevents her from making friends. Her only friends, however, are Alice, a girl who spends more time talking about her boyfriends than anything, and her mother, a wedding planner, and her father, a scientist. So, when Beth's father creates the first-ever time machine, of course she becomes excited. That is, until her father tells her she is not allowed to use it by herself. But, like almost all teenagers, she disobeys his wishes and goes back to the 1970's, where she gets a little more than she bargained for.
