In the den of "Koulou", as well as in other secret spots of the city, the meetings of the nationalist paramilitary organization take place. Under the guidance and blessings of the police chief, it has spread its tentacles throughout Thessaloniki. In such a den, the order for the assassination of the MP Z. Yatros, a distinguished athlete and advocate for peace, selfless, combative, and unruly, will be given. The execution is undertaken by Grylos, one of the henchmen of the death squad, with the accomplice Kabouras, a known pedophile. Time and place predetermined: Wednesday, May 22, 1963, at the intersection of Ermou and Venizelou streets, where a speech by Z is scheduled as part of an event by the friends of peace. "But you must be careful, be careful," we hear the Woman/Soul say anxiously.
