On a former German-German border section finds place a shoot to a feature film. Completely unmotivated plunges the actor Christian Blank on a colleague, a GDR border guard mimes. Only with difficulty he is separated from his victim and ends up in a psychiatric hospital - diagnosis "borderline syndrome". In retrospect, Blank told the psychiatrist, Dr. Wehmann his life. Even as a child he loved Jana. Later, they are a couple and plan to ask after studying for an exit visa from the GDR. But Blank receives his draft notice and must move precisely in the death strip "front lines". He always sits in the neck of the authoritarian and bullying joyful Major Nattenklinger. Of all these, he claims to have recognized on the set in his actor-colleagues. The more blank in his memoirs digs, the more clear, however, that he is not insane damage, but by his army past the soul. "Three Red Star" was flares signal and code-name of GDR border guards in an escape attempt on the German-German border. Screenplay writer Holger Jancke got the film idea during his military service, when in the freezing rain he complied the "duty of honor" and his sidekick expressed what he thought: "Who comes out here safely, is nuts".
