Fishermen spot in Wismar harbor a wine crate, containing live turtle Hermine, next the floating corpse of its devoted, retired owner, Willi Seeberg, unclear whether he drowned by cardiac arrest or the other way around after a fight. He accepted a few days earlier to pay 20,000 Euros ransom -advertised as reward, most of his life savings- for it, being the last gift of his late wife, stolen from his boathouse fridge (hibernating), perhaps mistaken for wine, but nothing else was robbed. Reuter mounted an extraordinary search for the animal as Willi Seeberg is an old angling friend. The team suspects young mates Eric Tiele, Thore Mayer and Lorenz Bock, who reacted on the reward advertisement. But his own son Klaas Seeberg desperately needed money for the house in need of constant repairs, after a failed career switch, his wife was told he got Willi to pay but they learned the armored memorial got priority.
