Inspector Thomas Bernhardt and Chief Inspector Anna Habel join forces for another investigation: They argue, tease and flirt like mad – but purely on a professional level, of course. Freddy Bachmüller, vintner in the Austrian wine region, produces first class wine – but now he is dead. Shortly afterwards, a local bar owner, Ronald Otter, is shot in Berlin – and he had Bachmüller's wines on his wine list. One thing is for sure, this case is ideal for the Berlin and Vienna investigator duo. Inspector Bernhardt knew the Berlin victim: they studied together in the seventies. Catchwords from back then come into his mind: the duty to disobey, to fight the system... And yet the conclusions which Bernhardt draws do not correspond in the slightest with Anna Habel's initial suspicions. She suspects that female jealousy lies beneath the case of the dead vintner. So are the two crimes not connected after all?
