Two older Hamburg police officers, who couldn't be more different, are transferred from their districts to the North German lowlands. In Kollmar on the Elbe, the two city police officers get to know a completely new life. "Every day, 200 to 300 people are reported missing. Every year, the BKA counts around 100,000 missing persons. Those affected often go into hiding voluntarily." (Source: BKA) The first story about the dike bulls shows where some of these missing people turn up again.
