人类对动物有着一种与生俱来的痴迷。千百年来，我们为了娱乐自己，将动物带离荒野，关进牢笼。动物园让我们有机会近距离接触那些我们通常无法看到的动物。但随着我们对动物行为的复杂性越来越了解，以及我们可以在电视上看到动物的自然生活状态，我们还应该继续把动物关在动物园里吗？莉兹?博宁是一名电视节目主持人，她同时也是伦敦动物学会的博士研究生，最重要的是，她还是一名动物爱好者。而她现在面临的问题是：二十一世纪的动物园到底该不该被关闭？

Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science or ultimately be consigned to history. 　　Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer. 　　But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them from stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.
