During Stalin’s reign of terror, Evgenia Ginzburg, a literature professor, was sent to 10 years hard labor in a gulag in Siberia. Having lost everything, and no longer wishing to live, she meets the camp doctor and begins to come back to life.

10-year-old Sota lives with his grandfather and a dog named Chibi in a small snowy village. They live in such a poverty that Sota cannot even afford to go to school, but however hard the situation is, Sota never holds a bad feeling against anyone around and keeps his dream alive to become a painter. He has been friends with Sayo, a girl brought up in a wealthy family, ever since they were little despite the difference of their family position, which Sayo’s father has uneasy feelings against. In spite of the difficulties he faces, Sota manages to complete a piece of painting which he wishes to give Sayo. He and Chibi goes down a snowy night path to Sayo’s house to find that her father’s storage is on fire… What waits for Sota and Chibi gently reminds that genuine happiness always exists in your heart.
