Ben gets involved in a bitter hunt on the highway. Gangsters persecute a man who, after Ben's intervention, can finally escape his captors. However, his car and his unusual cargo remain behind: domestic pig 'Arnold', which Ben now has on his cheek and turns out to be a key figure in a highly dangerous case. Semir and Ben can identify the fugitive as Marco Bernhartz, a zookeeper and former police officer who was previously involved in dubious machinations. Meanwhile, 'Arnold' not only develops a strong attachment, the supposedly harmless cattle also carry a secret that could cost the life of a member of the team. Ben and Semir have their hands full to avert the deadly danger and are supported by the attractive veterinarian Veronika. (RTL)
