之前，《绝代双骄》对《沧海龙帝》，虽然两边的读者吵得厉害，但是天启和司马二根本没有说什么。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.表面上无限风光的苏家，随着苏母的突然离世，瞬间分崩离析。意想不到的隐患层层显露，对毫无主见却又自私、小气的苏父的安置和后续生活问题，打破了远在国外的大哥与本城的二哥 、小妹三家的平静生活。父亲苏大强终于摆脱了妻子的铁腕，对几个孩子变本加厉，不断提出过分要求。在美国工作的老大苏明哲回到国内，一心要挑起家庭重担，却力不能及不堪重负，致使妻子孩子与其不断疏远。一直啃老的老二苏明成毫无悔改之心，贪慕虚荣一心发财，从而导致事业和家庭的双重惨败。最不受父母待见，十八岁起就和家里断绝经济往来的老小苏明玉，曾发誓与这个家庭划清界限，却因亲情牵绊，再次搅进了苏家的泥潭之中，在苏家的一次次危机中出手相助。最终，苏家人明白到，虽然有血脉相连，但是一家人彼此间的沟通也不能忽视，终于实现了亲情的回归。我们可能也曾面临过困境、也曾受到过伤害和由此产生的反抗，那种维护尊严的欲望和这些杀人者都是相同的，甚至更强烈。但有所不同的是，他们都采取了一种错误的方式。企图摆脱那种困境，却不料将自己置身于一个根本无法挽回的绝境，剥夺了给自己造成困境的人的生命，成了一名杀人犯。于是他们成了故事中的人。
