Four guards are standing in front of a high wall. They are waiting and keeping watch, without knowing why or for how long. Behind the wall is a state secret and everything is suspect, everyone a potential enemy of the state. ‘We see everything,’ they boast. They wait, they eat, they patrol and above all: they have no fear. But everything changes when one of them suddenly disappears and disrupts their unshakable rhythm. Routines that were once meaningful now lose all sense. The unexpected disappearance gets them thinking: why are we keeping watch? And above all: what’s behind the Wall? When their rigid choreography breaks down, the guards rediscover their personalities and their contact with one another.
