April 1941. The Germans after invading Greece, and despite previous assurances, allowed Bulgarian troops and guerrillas to enter into the Eastern Macedonia and Thrace. Progressively, the Bulgarians started terrorizing and exercising violence against the Greek population who opposed them. While this was happening, a Greek officer Nikos Devetzis, together with his friend, Vasilis Anthimos originating from the region of Eastern Macedonia, decided to return to their village which was under the oppression by a Bulgarian guerrilla group led by Stepan Rajko and started putting up resistance against the Bulgarian military forces and guerrillas.
