Hunkeler - Das Paar im Kahn

A summer of the century in Basel – but no vacation for Inspector Hunkeler. Instead of spending time with his partner Hedwig in Alsace, he has to take on a murky case: his family doctor, a liberal politician well known in the city, has been found murdered in her practice. A few drug addicts who had been supplied with methadone by her come under suspicion. But Hunkeler's instinct for the depths of the human psyche leads him unerringly down a different path.

Two dead with their earlobes slashed. Inspector Hunkeler believes that the brothel owner Garzoni is the culprit. However, his colleagues Madörin and Lüdi are researching the drug milieu. Then prosecutor Suter withdraws Commissioner Hunkeler from the case because of bias. Has Hunkeler grown old? The third film adaptation of a case with the Basel inspector Hunkeler based on the novel by Hansjörg Schneider.

Swiss allotment gardener Livius is murdered in his garden on French soil. The case must therefore be investigated by both the Swiss and French police. This leads to friction between the two forces. To make matters worse, Hunkeler has to cut short his vacation.

Hunkeler's last official act went awry: a diamond courier evaded surveillance, the goods ended up in the Basel sewage system, and Lüdi suffered life-threatening injuries. Plagued by guilt, pensioner Hunkeler goes in search of the "silver pebbles". Ultimately, even as a retiree, he is ahead of the pack with his sense of the longings of the little people.

Even in retirement, Hunkeler cannot give up investigating. In Basel, a theater director is murdered, and his body is found with its eyes missing.
