Then, the group finally gets a test-single deal with a record company. But it looks like there's going to be a fight for the spotlight. Next, just as they get a chance to be on MTV, Dorinda, a foster child, learns that she has a sister who is not only white but also coming to town. Finally, the band is doing their very first big-time concert. Do they have enough growl power to make it a success?
