The anesthetist Dr. Katrin Klein is new at the Dresden Transplant Center, which enjoys an excellent reputation. The star surgeon Prof. Gerhard Harrer works here. Katrin has known and admired the professor since her assistantship. But then her heroic image of Professor Harrer begins to falter. The young doctor seems to be the only one to notice that the luminary apparently has an alcohol problem. But nobody believes you. When Harrer finally collapses in the middle of an operation, he is suspended from duty. Katrin stands by him, but more problems are waiting in the clinic.
