Rav and Finn are whizzed from the Planet Zoom theme park all the way to Mars! It's very different to Earth - and it doesn't have as much oxygen! Soon they're running out of air to breathe and decide to leave the planet - but their spacecraft doesn't have any fuel left. Can they work out how to refuel the ship before they use up all their oxygen?
