Stefan has been building his own road-legal racing car for 12 years. Every Friday after work, he drives to his parents' house in Brandenburg to continue working on it in the garage. For him, this car is far more than just a vehicle, but his life's work and obsession. For him, there will never be an end to this work, because he is always trying to improve, optimize and prove that he can push the limits of what is technically possible one step further. David is also looking for a borderline experience. For him, this lies in the thrill of speed and vehicle control. When his rear axle breaks out at 100 km/h on a forest road, he feels alive. He uses the car to test his own limits. He accepts the risks involved. Die Schaltgetriebenen is a film about the power of passion, about the search for meaning and the urge to prove oneself.
