Outside the historic Asclepius of Kos, Sifis, Minas, and George, friends bound by "khaki" ties, will meet. A shadowy figure will arrive and without wasting any time will execute its purpose. The blood of the three friends will soak the ground.

The esteemed police officer Anna Dervisi will take on the investigation of the case. With the help of her close associate, Kyriakos Livathinos, they will turn back the hourglass of time and learn about the cynical profile of the victims during their military service. Meanwhile, some rusted cases in the police archive will serve as the lost pieces of an angry puzzle.

With immense patience and plenty of notes in her notebook, the police officer will trust her instinct’s call, until she confidently walks down the dark path of the killer. Just before the handcuffs, however, she will hear him plead for one last visit. Will Anna prioritize the "must" imposed by her ranks, or the "worth" that her humanity screams for?
