两个淘气的姐妹

　　一对黑人兄妹相依为命，哥哥却被白人警察误杀，你猜猜她会怎么办？对抗强权为黑人群体发声？并不，妹妹居然造了一架时光机器，回到过去好让自己的哥哥免于枪杀！

 故事发生在1977年2月8日，围绕一名44岁的前房地产开发商Tony Kiritsis展开。他用枪劫持了贷款公司总裁Richard O. Hall，并在其身上绑了一个“死亡开关”，以此胁迫这位总裁在几近零度的天气里当着警察和记者的面穿过市中心的街道。

　　The boisterous, arrogant professor Challenger, a reputed biologist and anthropologist, dares the London Zoological Society to mount an expedition to verify his spectacular claim, without physical proof, that his previous expedition to the Amazonian basin found live dinosaurs. Apart from him and his 'socialite' counterpart, professor Summerlee, it consists of experienced discoverer Lord Roxbury, the young reporter Ed Malone -who got publicly struck down with Challenger's umbrella at his arrival- and Jennifer Holmes, Malone's news agency's boss's daughter, essentially as conditions for putting up the money. In Brazil they are joined by Jennifer's brother David and local 'guide' Manuel Gomez. They soon discover the dinosaurs are real and dangerous, like giant spiders, but loose their helicopter and thus are desperate for a way down from the isolated plateau. They learn Roxbury knew about the fate of Burton White, an explorer whose diary they find, thus presume to be dead, in search of diamonds, and confirmation of the local tribe being the lethal guardians of the plateau's secrets, but also get surprising help...
