Synopsis:
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. Inspired by true events.

On August 15th, they told us we had lost the war. At that time, we did not really understand. Then one day, everything changed. Many soldiers, wearing uniforms we had never seen before, arrived on the island. That was the day I met Tanya.
