Tobias Buntschuh is a brilliant inventor. Physically, however, he is a cripple, an eccentric who lives withdrawn in his magnificent castle. But he doesn't hate people, on the contrary, he does a lot of good. He saves Lukas, a desperate young man, and takes him in. A young circus dancer also finds refuge with him on the run from her director. For the first time Tobias feels love and woos the young girl, who only feels drawn to Lukas. But neither of them want to hurt Tobias out of gratitude. But again it is he who renounces and strengthens her in her love.
