Private detective Hartwig Seeler is lured onto a false trail to Greece. Instead of a missing person, he finds himself confronted with his own fate and the unsolved mystery of his wife's death, years ago.

An assignment abroad takes Matthias Koeberlin, alias private detective Hartwig Seeler, to the wildly romantic coast of the Peloponnese peninsula - and into the wake of a mysterious case that confronts him with his own vulnerability. While his original mission increasingly slips away from him, the sensitive eponymous hero dives into an intermediate world of memories and illusions. Grimme award winner Johannes Fabrick staged the psychological thriller "In the Labyrinth of Revenge" as an emotionally charged hunt for a phantom that leads to a dramatic showdown and a surprising resolution. The picturesque landscape with mysterious grottos serves as the backdrop for the third film in the hit crime drama series.—ARD Das Erste
