The Rock

After being forced to flee from their home planet twins Zane and Finola find themselves on Earth. Dad is lost and Mum is no longer able to teleport, meaning that it is up to the twins to reunite their family. With such a large prize on offer for whoever is able to find the 'aliens', Zane and Finola can't trust anyone and must make sure that they never break cover on their tour of planet Earth.
