In post-war America, a German soldier named Klaus struggles to maintain a quiet life, haunted by his past and a menacing alter-ego, Krieg, who embodies his wartime trauma and seeks to disrupt his peaceful existence.
Klaus's mundane life is upended by Krieg's chaotic presence, who appears as a hallucination in a Nazi uniform, complete with yellow, X-shaped pupils, and a penchant for causing trouble.
Krieg's childish demands and violent outbursts push Klaus to the brink, as he grapples with the fear that his alter-ego will take over his body and plunge him into chaos.
The narrative delves into themes of trauma, identity, and the struggle between order and chaos, with Krieg's demands for a poppy flower serving as a catalyst for Klaus's descent into madness.
