Polt.

Real estate speculator Albert Hahn is found dead in his cellar. He died of fermentation gas poisoning. The doctor in charge assumes it was an accident. But Polt knows that the dead man was hated in the community. He suspects that the murderer wanted to make the death look like an accident. Many of the winegrowers had a motive. After a long investigation in the wine cellars, he discovers that all the cellars are connected by holes. Polt doesn't want to leave the feeling that it was a murder. As he drinks some wine with his friends, they all confess to the crime. They had all poisoned Albert Hahn with the fermentation gas together, but only one of them wants to take all the blame, as the rest have children and wives. He commits suicide and leaves a confession behind.

Gendarmerie inspector Simon Polt in the Weinviertel region finds it too much of a coincidence when crook Riebel is killed in a motorcycle accident and his friend Willi is found dead on the same day. But the residents of the otherwise peaceful Lower Austrian wine village make Polt's investigation anything but easy.

Policeman Simon Polt is on cloud nine. He finally has the village teacher Karin in his arms. But soon he's forced to look into the depths of humanity again: the priest's cook has been found dead. Was it the gourmet critic? The feisty woman had poured soup over his head the night before, in shock at the sight of an illustrious dinner party...

The film is based on the figure of the police inspector Simon Polt of the Austrian author Alfred Komarek.

Simon Polt (Erwin Steinhauer) is no longer a gendarme. Arrived in retirement, he participates cheerfully in the Weinviertel on village life. When a corpse is found after a feast, his sense of right and wrong again becomes noticeable. The police do not see any third party debt. He sees it differently.
