Two journalists, Adrian and the narrator, embark on a journey to learn off-road driving with the help of instructor Serge Nuques, a world-class enduro rider. They begin with a physical conditioning test, where they have to run while carrying a bag of sand. They then learn about proper driving position, where they are taught to stand up and support themselves on the footrests, handlebar, and legs.
The journalists are given two motorcycles to choose from: the KTM Freeride 250 F and the Yamaha YZ450F. They then participate in a series of tests, including cornering, navigating a "centrifuge" (a large, deep hole), and jumping. Throughout the training, Serge emphasizes the importance of speed, power, and proper technique in off-road driving.
The final test takes place on a professional motocross track, where the journalists apply everything they have learned. They face numerous challenges, including treacherous terrain, high speeds, and physical exhaustion. Despite struggling, they eventually manage to bring together their skills and complete the course.
In the end, the journalists are exhausted but exhilarated by their experience. Serge praises their progress, calling them "beautiful sand princesses," a compliment that is met with mixed reactions.
