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.
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.
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.
Hansi is elated and looks forward to a happy life when his childhood sweetheart Regina marries him. However, he is unaware that his rival is conspiring to cause a rift in his family.
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.
