第九区

1990年，一艘巨大的飞船出现在地球上空，人们惶恐不安，却又分外好奇。经过一段时间紧张的等待，外星飞船始终没有动静。人类终于小心翼翼靠近它，强行走进舱内，结果发现了不计其数的外星人。他们形容丑陋，宛如虾子，而且健康状况极差，虚弱无力。原来这是一群来自外星的难民，他们最终被地球人接纳，并隔离在南非约翰内斯堡的一片区域内生活，此地名为“第九区”。经过长达20年的繁衍，外星难民的数量扩张至180万之多，且和周边人类的矛盾冲突不断，越来越多的人类呼吁将“大虾”赶出地球。 　　MNU（列国同盟组织）经过磋商，决定将外星难民迁移到更为偏远的区域。MNU外星事务部门的特工威库斯（Sharlto Copley 饰）专门负责搬迁工作。威库斯在动员过程中傲慢随意，与当地居民冲突频频。最终，他为自己的行为付出代价，外星人的神秘流体将其感染，威库斯慢慢变成了外星人的模样……In 1982, a massive star ship bearing a bedraggled alien population, nicknamed "The Prawns," appeared over Johannesburg, South Africa. Twenty-eight years later, the initial welcome by the human population has faded. The refugee camp where the aliens were located has deteriorated into a militarized ghetto called District 9, where they are confined and exploited in squalor. In 2010, the munitions corporation, Multi-National United, is contracted to forcibly evict the population with operative Wikus van der Merwe in charge. In this operation, Wikus is exposed to a strange alien chemical and must rely on the help of his only two new 'Prawn' friends.
