Who could tell, in the first decade of the twentieth century, what strange adventures might befall those who ventured to travel by the new-fangled aeroplane? A forced landing, perhaps, in some long-forgotten land where time has stood mercifully still. James Smith, of the well-known London catering concern, drops in on Arcadia, where no-one tells lies, or grows older, where money is unheard of and unemployment a permanent attraction. Far from impressed by what Smith tells them of the joys of life in London his hosts despatch him, with missionary zeal-and two agelessly beautiful Arcadian nymphs-to convert the wretched metropolis. Things do not always go as planned.
