The worst band on Earth is George, Neila, and Bash. George wants them to be amazing, but Bash is too preoccupied with his obsession with stars, aliens, and distant worlds, and Neila has stage fright. But they make up for what they lack in talent and self-assurance with compassion. They intend to outperform their friends at the school's Battle of the Bands competition. But as soon as they begin to perform... They have been shot into space! The kids are now faced with an even greater obstacle: an extraterrestrial Battle of the Bands. They are up against extraterrestrial bands from every galaxy in competition! Furthermore, they might never return home if they lose.
