It has been a decade since Martin Gruber returned to his home in the mountains. He had a successful medical career in New York, but fate brought him back to Tirol. Today, his extensive professional experience benefits the people of Ellmau, many of whom require expert help. Martin Gruber’s approach goes beyond the purely medical, as he never loses sight of the emotional background of his work. His stubborn nature makes him unpopular with quite a few people – and, occasionally, the law –, but Martin could not care less. Martin Gruber lives on his family’s farm together with his mother, his brother Hans and his daughter Lilli.
After some time, Martin has now chosen Anne as the woman by his side and has proposed to her. The two are renovating the attic of the Gruberhof and want to start a family. But Anne has to undergo an operation after which she will probably no longer be able to have children. At the same time, Franziska returns to Ellmau to inform Martin of her pregnancy with his son. Due to a chain of unfortunate events, the planned wedding does not take place and Franziska decides to move to New York with her child, despite her rekindled feelings for Martin ...
Hans Gruber spends the little free time he has as a mountain rescuer. He and his brother, Martin, are an excellent duo of father figures for Martin’s daughter, Lilli. While they may not always agree on everything, they always pull together when it comes to her.
Hans now lives with Susanne and their daughter Sophia at Gasthof Wilder Kaiser. He has returned to the Gruber-Milch business run by his mother Lisbeth and Anne, works as a hiking guide and helps out at the inn. After Martin's receptionist Linn Kemper gets dumped by her boyfriend, she temporarily moves into the flat above the practice. Hans helps her to move in and feelings develop between them. Susanne finds out about the two and confronts Linn. Linn then hands in her notice and wants to leave Ellmau. Hans, however, professes his love...
Lilli lives at the Gruberhof with her two fathers, Martin and Hans, and her grandmother, Lisbeth. She has grown into a confident young woman and made a plan for her future: she wants to split her working hours between the family farm and Martin’s practice. But her initial euphoria is soon dampened by frustrating routine: she barely has any time left for herself. Lilli starts wondering what it is she wants from life.
After her stay in New Zealand, Lilli starts an apprenticeship at Martin's practice and is now allowed to take care of the patients more often. After some time on her own, Lilli startet dating the patient Robert Schwarz. They meet several times until she lets him spend the night at the Gruberhof, and her family gets to know him as well...
Lisbeth Gruber enjoys having her sons, Hans and Martin, and her granddaughter, Lilli, around her. She is the go-to person for worries and problems and also has to reprimand her sons from time to time.
Together with Anne, she founded the brand "Gruber-Milch" and even though obstacles were put in their way at first, the two women managed to save the company. Son Hans also gets actively involved in the business again...
Susanne, the innkeeper of the Gasthof Wilder Kaiser inn, is an honorary member of the Gruber family. Her relationship with Martin ended in tears as her then still legally wed husband suddenly reappeared, but she and Martin have managed to talk things through and are now close friends. Having tried and failed to save her marriage, Susanne fell deeply in love with Hans Gruber. They had a daughter, little Sophia, and were determined to do everything right – but their relationship did not stand the test of time.
Susanne eventually rekindles her love life with Tim Petersen, who wants to take her and daughter Sophia to Vienna. But Susanne hesitates to accept and then stays in Ellmau after all. A short time later Susanne and Hans find each other again and Hans moves in with his family. Susanne, however, becomes more and more preoccupied with the inn and their time together as a couple becomes less and less. When Hans and receptionist Linn become close, Susanne tries to get her to quit. But then Hans confesses his love and leaves Susanne...
Linn Kemper has been the receptionist in the Bergdoktor's practice since season 12. She is a great help to Martin with her medical knowledge. She also actively helps with the renovation of the practice and the flat.
After a painful break-up with her boyfriend, Martin lets her move into the flat above the practice. Hans helps Linn with the move and the two become close. They meet again and end up in bed one evening. The relationship between the two does not remain undiscovered. So first Lilli confronts her and then Susanne, who demands that she resign and move away. Linn realises that this is probably the best thing for Hans and his family and hands in her notice to Martin. But then Hans confesses his love and wants to give their relationship a try...
For a while, Anne Meierling thought that she had found the love of her life in Martin Gruber. But her father, Arthur, could never stand Martin and was hell-bent on preventing their bliss: he went out of his way to sabotage the couple. Now, Arthur has passed away, and Martin cannot forgive Anne for asking him to lie to the insurance company for her. He finally decides to break up with her and put a stop to the endless back and forth. When his family informs him that Anne is about to move to the Gruberhof to work there, Martin does not hesitate to leave the family farm. Anne is not pleased: she still has feelings for Martin and refuses to give up on their relationship.
While Anne is warmly welcomed to the farm by Lisbeth and Lilli, there are repeated arguments with Hans. He finds it difficult to accept Anne as an equal partner and ignores her in important decisions. After an argument with Martin, Anne leaves the farm in a rage, rents another farm and takes her fields with her. Hans then wants to sell the Gruber farm. At the last moment, however, Anne steps in, founds the "Gruber-Milch" brand with Lisbeth and thus saves the Gruberhof. Anne and Martin slowly get closer again and their love rekindles. After they have overcome a few hurdles together, Martin spontaneously proposes to Anne. The two of them look forward to the wedding and build out the attic at the Gruberhof. Soon the subject of children comes up. But Anne has to undergo an operation, after which she will probably not be able to have children.
Then Franziska, Martin's ex, re-enters their lives and it turns out that she is expecting Martin's child. Anne comes to terms with the situation, but does not want Franziska to come between them. Through a chain of unfortunate events, the planned wedding does not take place. Franziska, however, decides to move to New York with her child ...
Dr Alexander Kahnweiler is the senior physician at the Klinikum Hall hospital and Martin’s most important partner when it comes to looking after his patients. Their initial rivalry has given way to a friendship that keeps getting Kahnweiler into trouble: whenever Martin plays fast and loose with the law, Kahnweiler allows himself to be dragged into his breakneck missions. He protects his colleague from the scrutiny of his boss and life partner, Dr Vera Fendrich.
His relationship with Vera is far from perfect: the couple endlessly falls out and reconciles. The question of children keeps dominating their life together. Vera is infertile. After some discussion, however, they take in a foster son, whom they later adopt. Alexander is attracted to the position as head of surgery, but Vera decides in favour of his competitor Dr. Johanna Rüdiger due to funding. But when she applies for another post immediately after being appointed head of surgery, luck is again on Alexander's side and he is appointed head of surgery.
Dr Vera Fendrich joined the Klinikum Hall hospital when her father still managed it. Her unapproachable demeanour tends to keep potential suitors at bay, but Alexander Kahnweiler dared to go on a date with her – initially prompted by his boss’ suggestion and the prospect of a promotion. Their relationship developed slowly but surely, and while it is often fraught with difficulties, the two always stick together. When Vera finds out that she cannot have children, she works hard to process and accept the fact, but Alexander surprises her. After being strictly against adopting a child at first, he is suddenly keen to do just that. The two of them do just that and take Jens-Torben to live with them.
In her position as deputy manager of the clinic, Vera frequently has to remind Alexander and his friend, Dr Martin Gruber, to stick to the rules. But their enthusiasm for their work is infectious. Vera is a valuable member of her own department, the laboratory, and quick to act when she is needed.
