The movie starts with a blond female singer who goes back home for a family emergency. She returns to find her brother still mad at her for breaking up the band. There could have been another brother but it was a long time ago. At some point in the film the power goes out and the female finds her song book she had for the band, her and the brother start singing together. The band gets back together and they sing together at a concert in their hometown. The movie was set during the summer in a small town and I first saw the movie on the old freeform channel. Sorry for the lack of information, I haven't watched it in years
