柏林是一个富有想象力的地方，一个记录所有历史的城市。当柏林墙于1989年倒下时，柏林人在历史长河中的慌张之旅告了一段落。在本节目中，间谍、告密人、双重间谍和冷战柏林墙的讯问者讲述了自己紧张不安的双重生活，梦想与梦魇戏剧般地重现出来。柏林墙是一道丑陋的混凝土屏障，它分开城市，分离家庭，足足影响了一代人（1961-1989年）。几百人（大部分是年轻人）因为试图逃往西柏林而被杀死。建造柏林墙的人认为，他们建设了一个英勇的社会主义世界。但是，柏林墙不断毒害、腐化、残害包围在它里面的人，建造者的梦想变成了梦魇。　　Berlinisaplacethatisindispensabletotheimagination,acitywherehistoryticksalltheboxes.Thelongestofallthehelter-skelterridesthatBerlinershavetakenthroughtheplaygroundofhistoryendedin1989whentheBerlinWallshatteredintoamillionsouvenirs.　　TheBerlinWallwastheugly,concreteobstaclethatformorethanageneration(from1961to1989)splitthecityanddivideditsfamilies.Hundredsofpeople,mainlyyoung,werekilledtheretryingtoescapetotheWest.　　ThepeoplewhobuilttheWallthoughttheywerebuildingabravenewsocialistworld.ButtheirdreamturnedintoanightmareasovertimetheWallpoisoned,corruptedandbrutalizedthelittleworlditencircled.　　InTheSecretLifeoftheBerlinWall,thedreamsandnightmarescomedramaticallybacktolifeasthespies,informers,doubleagentsandinterrogatorsofColdWarBerlinweavetheirnervyspellsofdoublelivesanddoubledealing.　　Wallsdividetheworldintotwoandthisisafilmwithtwofaces-flawedheroesandheroicvillains,traitors,compromisedvictoriesandsaddefeats.Aworldofgoodintentionsheadinginbaddirections.Aworldwherenothingiswhatitseemstobe.
