2020. The Covid-19 pandemic strikes the world. In Marseille, Professor Didier Raoult claims to have found a miracle cure: hydroxychloroquine. Within weeks, the scientist becomes a star in France and a global phenomenon. But six ordinary people—teachers, researchers, and healthcare workers—decide to verify his claims. Banding together on social media under the name "Cerises Trottinettes," they embark on an investigation they were never meant to undertake. Amidst a battle fueled by a cult of personality, disinformation, and death threats, their quest for truth turns into a brutal standoff. To make matters worse, within the "Cherry Gang," Magali—one of the most committed members—is hiding an explosive secret: she is Didier Raoult’s own daughter.
