He was unmarried and childless. Aban did not like to live in conformity with the rules. In 1905, when he was just in his third year at Stanford University, he dropped out of school to join the society and got a job as an intern reporter. Before coming to China, he had been immersed in the US press for 21 years, and the highest position was editor-in-chief. During this period, Aban did not consider getting a wife and having children. He just changed jobs frequently and wrote in the mountains. In short, he hated any fixed day. After all this trouble until I was in my early 40s, I suddenly had a whim to enter the world in the Far East and came to China.马里斯特拉扎被称为建筑界的艺术家和大师，他所设计的建筑被同行奉为典范。在某个，一幢马里斯特拉扎的代表作拔地而起，然而这里却发生了惨绝人寰的凶案。许多无辜之人被砌在墙壁中，浇筑水泥窒息而死，这幢大楼也从此废弃。15年后，年轻美丽的女拆迁工程师萨曼莎（Mischa Barton 饰）自学校毕业，她从父亲手中得到拆毁那幢大楼的任务。萨曼莎独自一人前来，在这里认识了女管理员玛丽•苏特（Shannon Jardine 饰）和她的儿子吉米（Cameron Bright 饰）。从母子的口中，萨曼莎得知这幢大楼的一些禁忌，而在吉米的引导下，她逐渐发现这里阴暗的一面……因为他想，他好歹跟高凡有些渊源，到时候也能见机行事。该剧由12个独立的故事结构而成，每个故事都以一位进城打工的农民工为主线，描写他们的喜怒哀乐、爱恨情仇，真实展现他们背井离乡在城市生存的孤苦无奈：进城做保姆的农村妇女深陷婚姻牢笼的悲惨境遇；顶着风险辛苦帮人开黑车却被拖欠薪水的农民司机；处处想帮人解决问题却招致祸端的小区保安；进城打工妻子却遭遇性骚扰的夫妇。悲剧故事的背后，是这些城市边缘人被忽略的自尊，被轻视的命运和他们对融入城市的热切渴望。那个周智整个人就像个机器人。尽量吧。
