Nine year old Harry has a plan. A plan to build a rocket and fly his mum to safety just like his hero The Star Ship Captain from his favourite TV show. With only his best friend Jordan by his side, can they blast off before it's too late?

After losing control of his engines, bumbling spaceman Fripp finds himself at the mercy of his spaceship. A thrilling descent through an asteroid belt ensues, after which he finds himself marooned on a post-apocalyptic Earth. Without a working spacecraft, the interstellar time-traveler must dip into the dead planet’s history in order to find a way home.
