Whose is this song? is a funny, dramatic and tragicomic search for the truth about a Song. A Song that everybody in the Balkans claims it is theirs.A Song that appears as a love song, as a religious hymn and even as a song inciting for battle. An exciting journey around Turkey, Greece, Macedonia, Albania, Bosnia, Serbia and Bulgaria. A film showing with a sense of humor some of the typical features of the character of the people on the Balkans, as for example their habit of appropriating all that is good and denying the others the right to possess the same qualities, the same songs, the same customs, the same temperament.
