While walking along the beach one day Isobel & Nicholas discover a strange looking wreck. As they begin to put it together they find it is a peculiar sort of sailing boat. They clamber in & so begins their great adventure. Aided by a wounded stork they sail through the sky encountering scenes of despair & devastation & set about righting some of the wrongs in the world. At each place they stop to help & soon the boat is full with all their new friends
- a bullied girl a weak child worker a boy rescued from a polluted city a mother & baby saved from a war zone. But this all takes its toll on the boat & they have to find a safe place to land where they can all work together to build a bigger & better sailing boat & continue on their humanitarian mission.
