Fear (1954) follows a scientist who, devastated by his wife's affair, conducts gruesome animal experiments using poison as a coping mechanism. As his wife becomes entangled with a factory owner, the scientist's jealousy and desperation escalate, leading to a thrilling climax.

In spite of his blustering manner and his refusal to listen to what the patients have to say, Dr. Doppelsieder is highly respected in the Upper Bavarian town of Bayrischzell, because he (almost) always has the right remedy and effective advice ready for the sick. The only person he can't help is Pfundtner, the rich Guldenhof farmer. He wants a remedy that, after seven daughters, will finally help him and his wife to the longed-for farm inheritance.
