"We solemnly swear to seek adventure, excitement and danger and to rescue anyone in peril." So proclaim the Freewheelers, Gina, Claire and Mandy, as they set out on a new adventure - to stop aliens taking over the world! No one believes them when they try to warn the world about the danger it faces. It is up to the Freewheelers to act alone! Can they stop the aliens before it is too late - or will their plans go wrong as usual?
