From the introduction:
This game lets you create and live out your own episodes of l'explorateur du futur for an audience of listeners, in the form of a radio drama.
At the beginning of each episode, the Dragonfly lands on a new world. It doesn’t take long before the Professor notices a terrible danger is afoot... Leaving his Assistants behind, he leaps in to save the day… and ends up in an inescapable mess...
Each player portrays one of the Professor’s Assistants. It’s up to them to find the Professor, get him out of trouble and let him save the day!
