Kyiv is under the rule of the Bolsheviks, Europe is recovering from the Great War, Egypt\'s cabarets are luxuriating with nightlife, and Herr Friedrich leaves his pupils a will - a riddle that will lead them to the treasure. In order to fulfill the last will of the named father, the former pupils of the \"Artemis\" shelter gather again as a group and set off on a dangerous and adventurous voyage through the Mediterranean Sea. Each of them has their own experience of the war and secrets that they keep even from their closest friends. During the sea expedition, four female spies will visit four temples of Artemis, arrange a spiritual session, meet a Turkish fortune teller and dance on the stage of an Egyptian cabaret. And most importantly, they will compete with their own demons and definitely defeat them.
