Lumière, caméra, sauvons la Vallée des Aigles!
Movie star Boris Tête-de-Bélier is making a film in the Vallée des Aigles, and everyone is delighted. Well, almost everyone. It turns out that Simon once directed Tête-de-Bélier in a film and was fired for standing up to the tyrant. When Luna is chosen to be his co-star, the owl has stars in her eyes and refuses to see the harm Boris is doing to her friends and the Valley of the Eagles. After trying to persuade their friend that the film is a bad idea, Bric and Poulpi are horrified to discover that once the film is finished, Luna intends to leave Eagle Valley and move to Joliwood. Is this the end of Les Aventuriers?
