In the final days of the Pacific War, two Japanese soldiers, a senior officer and a local recruit, are cornered during the battle of Okinawa and hide in a banyan tree, only coming down for food. Unaware the war has ended, the two await reinforcements for two years. As they wait, they discover differences in rank, worldviews and motivation.

The 2016 edition of PRISON is the omnibus horror film by an Okinawa-based filmmaker. This splatter series is full of extreme shocking depictions that have terrified horror fans in Okinawa. Includes two films, "Inga" and "Sin Walks in the Night".
