In this interesting World War I drama, Bruno Ganz gives a compelling performance as Jakob, an obsessive inventor who lives in a Swiss village. He receives unconditional support from his friend Otti (Walo Luond), but that is about all; the other villagers do not tolerate Jakob's eccentricities very well, and regard him as a crackpot. He perserveres in spite of this obstacle and finally invents a viable carriage that does not run on wheels but on a tread. Unfortunately for Jakob, the military have already come up with the same invention: the tank. The discovery finally breaks him, and he is quickly shuttled off to an asylum.
