旧金山的最后一个黑人

　　丽兹（索拉·伯奇 Thora Birch饰）出生在美国的贫民窟里，从小就开始承受着家庭的千疮百孔，父母酗酒吸毒，母亲患上了精神分裂症。贫穷的丽兹需要出去乞讨，流浪在城市的角落，生活的苦难似乎无穷无尽。
　　随着慢慢成长，丽兹知道，只有读书成才方能改变自身命运，走出泥潭般的现况。她从老师那里争取到一张试卷，漂亮的完成答卷，争取到了读书的机会。从现在起，丽兹在漫漫的求学路上开始了征程。她千方百计申请哈佛的全额奖学金，面试时候连一件像样的衣服也没有。然而，贫困并没有止住丽兹前进的决心，在她的人生里面，从不退缩的奋斗是永恒主题。

　　Massive machines require engineering extremes.
　　The massive man-made satellite, commonly known as the International Space Station, hurtling around the Earth at 27,600 km an hour, has been a temporary home for humans for the last 20 years. The biggest land vehicle on earth, a bucket excavator titled Bagger 293, that can move 240,000 cubic meters of dirt each day. Innovation has always meant building bigger, faster, taller, longer and stronger than anything that came before. We’ve seen them in dramatic visual fashion. But how do these actually work? What sets each machine apart. What big ideas drove its evolution and what limitations did this machine overcome? What forces was it built to withstand and where is the breaking point? Using CGI and expert insights, we ‘strip down’ the design of some of the world’s unique colossal machines and reveal mechanical secrets that not only made them work, but also changed the world in a big way!
　　Each episode explores four incredible machines, linked thematically. From sea and space faring designs, to mega airborne, mining and industrial machines, we’ll break down what they can do as well as key inner mechanics and materials that make it all possible. Dynamic archival footage featuring; slow motion, aerials, and time-lapses get us past the ‘caution’ tape and up close and personal with these compound monsters. CGI provides breakouts and blueprints and a look at hidden mechanisms. Adding expertise of structural, mechanical, chemical and forensic engineers to help reveal what’s at stake when these colossal constructions are put work, and how all the pieces come together to make a big impact.
