Travelling by airship is supposed to be slow and boring, but this voyage is a lot more interesting than the passengers aboard Handley Aviatrix bargained for. With the passengers in the hands of hijackers, the crew helpless and Handley Avatrix herself on a collision course with destruction, it falls to the travellers to save the airship and themselves. They must confront gunmen, treachery and airsick rodents at high altitude over an acrtic sea.
