In the year 2447, the Empire of Earth faced the most serious threat to its existence since its formation... Already, 89 top agents had been killed in abortive attempts to put an end to this interstellar menace. So it was decided to call in Jules and Yvette d'Alembert – the two greatest aerialists in the Circus of the Galaxy who were also highly qualified specialist security agents.
