Petros Antoniou is a determined police officer with an inexhaustible instinct but also a guilty past that he wants to forget. His path leads him to Angelochori, a mountain village at the foot of Mount Olympus, as the chief of the local police department. Together with his life partner, Dimitris, they moved there to get away from the hustle and bustle of the city and live a more secluded life.
