ROCK IT! takes a pop group to where no pop group has ever gone before: to outer space! Jack, Comet and Asteroid, three inquisitive friends, are accidentally launched into outer space when they discover what they think is an old rocket ship ride in an abandoned fairground. On board, the group makes new friends in Cosmos and Zaboo, two loveable aliens, and Gamma, the galaxy's greatest computer. Together, they form the coolest pop group this side of the Milky Way - ROCK IT! - and they're headed for adventures of galactic dimensions!
