Silberkiesel - Hunkeler tritt ab

Plot: 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.
