Luke, Yasmin and Yuri have been stuck on the Buzz Aldrin spaceship for so long that they can barely remember what living on polluted planet earth was like! So when the colony finally finds an earth-like planet that seems safe to land on, they can't believe their luck. But when the trio of friends accidentally stumble across an abandoned alien city, tripping the planet's self-destruct system in the process, it seems that all their dreams of leaving life in space behind are about to go out with a bang. Can they save the planet, or at least save themselves, before blast off?
