Mentally challenged criminals can not be held responsible for their actions. They do not belong in jail, but it is where they often end up, in the absence of an alternative. Without treatment and without perspective, their release date is December 31ste of the year 9999. Time loses all meaning here. “9999” takes you to a forgotten part of Belgium and looks some internees, languishing in the prison of Merksplas, straight in the eyes. A candid, intimate and often poignant portrait of people whose lives are stationary in time.
