Savannah, Rosemary, Valorie, and Trish are in a band, and perform at their school talent show. They didn't win, and they were disappointed until they meet a music producer named Gustavo at their favorite hang out, Ice Cream Cafe. Gus asks Savannah if she wants to be famous, which they all knew was a dumb question. So the 5 of them go to LA and there the 4 girls ran into their favorite band 'Big Time Rush', who help them move in. The guys' girlfriends got jealous and broke up with them, leaving the guys single and sad. Savannah, Rosemary, Valorie, and Trish help them get through it and end up dating them. Both bands go on tour, originally seperated until Big Time Rush convinces Gustavo to make the tours together. Will both band make it to the big time, or will they fight and the tour gets cancelled?
