WaPo Duisburg S01E05 - Juwelenräuber

Jeweler André Fischer is robbed. The police immediately block all roads to prevent the thieves from escaping.

But there is a security gap: the harbor. Thanks to Jäger's keen instincts, the colleagues from the "WaPo" give chase and are able to stop a suspicious ship. But it's not just the jewel thieves who are on board, but also Frank van Dijk's father! He is the captain of the ship.
