A routine operation takes a dramatic turn when Dr. Jutta Lambertz tells operating physician Dr. Blessing that he is making a mistake. He ignores her comment - a fateful error, since the patient dies that night. As the patient had been assaulted by his rival, this man, Grünewald, is accused of manslaughter. Among everyone present at the operation, only Jutta has the courage to tell the truth and save Grünewald from an unjust sentence. This leads her on a collision course with Blessing and the hospital, which jeopardizes not only her career.
