An emotional WWII drama from Production I.G in the vein of GRAVE OF THE FIREFLIES.

Based on the true untold story of the Soviet occupation of the Kuril Islands at the end of WWII and the trials experienced by the region's tragically displaced Japanese inhabitants. In the aftermath of the most devastating conflict mankind had ever experienced, the tiny island of Shikotan became part of the Sakhalin Oblast... and on the unhealed border in this remote corner of the world, friendship among children from two different countries timidly blossomed, striving to overcome language barriers and the waves of history.
