After Spring, the Tamaki Family...

The film follows the last 4 years life of Grandma Hashima, the last existent from colonial Taiwan, who knows the secrets of "Green Jail," the notorious coal mine before World War II in Okinawa, Japan.

Green Jail

Taking place in the 1930s on one island of the Japanese Empire, a few Pinginumu or the ‘escapees,’ attempt to flee from the infamous Green Jail coal mine but lose their way. They suffer from starvation, risk a brutal beat-up if caught, or if lucky, they swim to regain freedom. They become the hungry wandering living-ghosts. After the war, locals have more or less witnessed the miners’ ghosts that remain wandering about, as if they were still the poor souls that lost direction.
