The man whose body washed up in the Neckar was seriously ill and clearly drowned. However, external influence cannot be ruled out and so Thorsten Lannert and Sebastian Bootz begin investigations. Wife, son, the craft business in a village, friends, Matthias Döbele's life is examined for suspects. The inspectors are irritated when they realize that forensic pathologist Daniel Vogt recognized the dead man as a childhood friend during the examination, without sharing this knowledge. Even more irritated when they get the impression that Vogt didn't examine the dead person thoroughly enough. The case seems to be causing lasting concern for her otherwise calm colleagues. Thorsten and Sebastian don't know that shortly before his death, Matthias Döbele had asked his childhood friend Daniel Vogt to call him back in vain. This omission leaves Vogt no peace. Instead of sharing his knowledge with the inspectors, he begins to investigate himself in his hometown.
