在这部BBC自然界：铁幕下的生机纪录片片中,铁幕政权把欧洲分裂成两部分，东边奉行共产主义，西边则是资本主义。20年前当这道残酷的屏障打破后，却留下了一个佯谬，这条欧洲的脆弱防护带，保护着它的野生动物远离现代文明的蹂躏。这个故事讲述的是铁幕如何成为这个世界上最大的野生动物保护工程。如何从死亡地带变成生物的避难所。
The physical, ruthlessly guarded Iron Curtain between the free West and Soviet block was a nightmare for people, but a sanctuary for wildlife, some of which thrived nowhere else. After the fall of the Berlin wall, biologists research how birds, and other species, fared in the former no man's land, first in Germany, then further south.
