In the forever-warring neighboring countries of Centi and Groshia, lovers Zigmas and Jadze live. At night, they walk through the border that is guarded by the same friendly 'kumas'. One morning after a stormy night, Groshia's mayor Varnalesha accidentally falls into a sewer pipe carelessly left open on the street. Looking for culprits ('Assassination!'), he points fingers at Zigmas and Jadze seen among the crowd, and thus begins another military conflict between the countries.
