Gerri waits outside all night to audition for Big Time, her favorite TV singing competition. She believes she has a shot at success, but when she's insulted by one of the judges and kicked out of the competition, she thinks she'll probably never sing again. After a teacher at her school asks her to join a choral club, Gerri reluctantly gets involved. Even though she can't read music and she doesn't know the other kids, she finds herself enjoying the group and learning a lot about music. A cute guy she met at the Big Time auditions joins the group, and when they perform their unique mashups at an open-mic night, Gerri realizes there's more than one way to be a successful--and happy--singer!
