Tatort S2008E31 - Dellwo - 14 - Der tote Chinese

The body of a naked Asian-looking man is found in the airport hotel's fitness room, his larynx crushed by a barbell. Singer and Dellwo are faced with a seemingly unsolvable mystery, because there is no clue as to who the man is, where he came from and why he was killed. A first clue is a trade convention at the airport hotel, attended by more than 600 Chinese. Singer finds out that on the night of his death, the victim was sitting with three conventioneers in the hotel bar and then got into an argument with them. In the meantime, a nervous Chinese is trying to check in with his passport and ticket at Frankfurt Airport. He came across the body as a cleaner in the morning and looks exactly like the murder victim.
Now he wants to take advantage of the similarity and get to the United States with the dead man's papers. But when the Chinese wants to go through passport control, someone snatches the papers from his hand. Someone who is looking for him - or rather, looking for Tony Wang. Finally, Shavkat Nazarow brings some light into the darkness. He tells Dellwo about a deal that the dead Tony Wang had offered him: Somewhere in Frankfurt there is a container with Chinese refugees without food and water. Singer and Dellwo realize that they are not only dealing with a murder case that can hardly be overlooked, but also with a harrowing race against time.
