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.本剧讲述三个特种部队的优秀军人，退伍 后走上不同道路的故事。　　年轻重案组督察何铁男（周文健），凭着天生侦探头脑屡破奇案，在警界早已享负盛名。不久，铁男组别接受了新晋CID Jacky（徐濠萦）毛遂自荐，首天上任，她即遇上了一件匪夷所思的怪事——一只流浪狗前往警署报案。赵天豪（狄龙 饰）是中原镖局的总镖头，雷大刚（汪强 饰）和杨云翼（龙隆 饰）是他的结拜兄弟，左膀右臂。赵天豪有三个女儿，赵琪瑛（应晓薇 饰）、赵梦娇（林秀玲 饰）赵燕翎（杨丽菁 饰），赵梦娇喜欢着雷大刚的义子郑青山，可是郑青山却钟情于知书达理的赵琪瑛，无奈赵琪瑛早已经有婚约在身。这些年来她一直在和两位抚养自己长大的女人一起看爱情肥皂剧——她性感的、心态年轻的母亲Xiomara（Andrea Navedo），还有仍然对肥皂剧痴迷的外祖母Alba（Ivonne Coll）。肥皂剧中虚无缥缈的爱情在某种程度上影响了Jane的爱情观，让她对现实生活中的爱情也产生一种不切实际的幻想。不过她绝不会犯母亲曾经犯过的错误——在16岁时未婚生育。7-4, 5-6, both dead
