Chief physician Leo Leu is under a lot of pressure. In a few minutes, he is supposed to give an important speech at a neurology conference. If he messes it up, he can kiss his ambitions of becoming clinic director goodbye. But he keeps getting interrupted. A Christmas party needs to be prepared, rehearsals for a nativity play are coming up, and a colleague is pestering him: Doctor Leu should be so kind as to play Saint Nicholas. In the midst of this chaos, former nurse Rita Kuster bursts in and confronts her ex-boss Leu with his sensual past. Leu reacts as quickly as he does clumsily: he lets assistant doctor Blättler in on the secret, who is supposed to take the blame for him. But an overexcited teenager, a gruff head nurse, a curious police officer, and a shot of Valium throw a wrench in Leu and Blättler's plans.
