Plot synopsis: Bonn depicts the rise of the young West Germany, a country struggling to break free from the terrors and legacies of World War II and longing for a 'normal' life. Into this heady and volatile mix steps Toni, a young woman determined to seize every opportunity, overcome every obstacle and make her own way in what is still a very male-dominated society. But what at first appears to be only an entry-level office job at one of the country's two competing secret services soon sucks her ever deeper into a clandestine world of secrets and suspicion. Based on true events.
