Veterinarian Hansi Riedlinger emigrated to Australia many years ago. At the request of his mother Marianne, he is now returning to Kaisertal to give his father Johann a hand. After an expensive renovation of his stud, the stud ran into financial difficulties and the farm was threatened with loss, because Mayor Ludwig Hackl asked for his loan back earlier than agreed. Johann is up to his neck, but he doesn't want to be helped. To this day, he has not forgiven his son for turning his back on the common veterinary practice. Hansi tries to support the father anyway, but the malicious Hackl lets him down coldly: He wants to finish off his former best friend Johann - because of an old feud.

Hansi Bruckner is the owner of a riding stable in the Austrian Alps. His wife, who used to work as a doctor at a local orphanage, and who had left him after the death of their child, is now returning home and they want to try to overcome their differences and come to terms with past events.

Hansi Sandgruber is on the trail of a dangerous poacher and asks the new mayor of Schönbichl, Lois Mostberger, for help. However, Mostberger is much more interested in the latest project of the sophisticated businesswoman Viktoria Perterer: the construction of a covered ski slope. As her first official act, Mostberger closes the retirement home, which is in need of renovation. This brings Hansi's girlfriend, the TV reporter Christl Huber, who is committed to helping senior citizens, into the picture. Meanwhile, Viktoria meets the well-off Baron Friedrich von Lien, from whom she hopes not only financial support but also a romantic relationship. While Viktoria already fancies herself a future baroness, von Lien has fallen in love with the attractive geriatric nurse Lisa Blum. Due to an intrigue, she is suspected of being a poacher and is taken into custody – until Hansi catches the real culprit.

After Hansi's sister and girlfriend want to move to Munich for their respective reasons, he decides not to be a hurdle in their path and let them pursue their goals.

Damn it, life isn't kind to Hansi: his wife dies in a mountain accident. The cheerful Tyrolean becomes a taciturn man. Only the pretty radio presenter Christl manages to melt the widower's frozen heart – up in the mountain hut. Reason enough for Hansi's adversary Viktoria to sabotage the young couple's happiness...

The mayor would like to snatch the Moosburg Castle under the nail so that he can move his club "Paradies" and the "Damen" there. But the Reverend has other plans: he wants to build a children's home in the castle. Only the rightful heir, the young pediatrician Dr. Seefellner can help him.

Christl and Hansi Sandgruber return from their vacation in Australia. A lot of work awaits them, as the wildlife park's 30th anniversary is coming up. Hansi's arch-enemy Viktoria Perterer is going through less rosy times, having gone bankrupt overnight after reckless stock market speculation. Unexpectedly, a rumor surfaces that old Sandgruber may be responsible for the unexplained death of Viktoria's beloved father, who died in a mountain accident. Hansi is outraged by this suspicion of his father, but there seems to be evidence to support it.
