Minoru, serving a life sentence, awaits a lonely death in his prison cell. The only real sign of life in the cell is a potted balsam flower - hosenka in Japanese. One night, Minoru begins sharing his life story with the flower that, improbably, talks back.

With the company of his unexpected confidant, Minoru reflects on his past as a low-ranking yakuza member, the decisions that led him to prison, and the meaning of life and love.

A tender, critically-acclaimed anime from the creators of hit series Odd Taxi.
