In 1941, sixteen-year old Lina (Bel Powley) is preparing for art school, first dates and all that summer has to offer. But one night, the Soviet secret police barge violently into her home, deporting her along with her mother and younger brother to Siberia. Lina's father gets separated from the family and is put in a prison camp. Lina fights for her life, fearless, vowing that if she survives she will honor her family, and the thousands like her, by documenting the experience in her art and notes. She risks everything, hoping that her messages in art will make their way to her father's prison camp to let him know his family is still alive.
