　　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...

　　跨國投資銀行香港高層約翰收到勒索電郵，如不按指示三日內交出約十九萬港幣，有關臺灣科網龍頭公司之機密融資分析就會被公開。為了公司聲譽，也為免客戶股價大幅波動，約翰暗中找來昔日大學舍堂堂友兼刑警唐輔協助調查。　　機密融資分析由約翰四位下屬負責，其中牧野一度失蹤，嫌疑極大。發現檔案在內聯網被偷之小儒，因曾向電腦部職員阿植求救，結果整個團隊連阿植六人，都被約翰安排到附近一間貴賓公寓套房，接受唐輔以至其手下全天候監視，直至完成贖金交易。　　由于贖金奇少，綁匪顯然志不在錢，其多個古怪指示更令人困惑。當阿植協助追蹤綁匪電郵源頭時，竟發現電郵是由公司伺服器發出，換言之綁匪必有內應。其后電郵證實來自阿植手機，縱然他在早上已遺失手機，而最后是小儒接觸他手機，阿植依然百詞莫辨。　　唐輔發現阿植家庭背景殊不簡單，疑似內應之神秘人又頻頻現身，加上科網公司原來曾有高層因新一代網上平臺開發延誤而被迫離職，甚至行蹤成疑，這一切都有關連嗎？　　由開發延誤導致融資失敗，由此可能觸發新一輪全球股災，到最后綁匪竟要求用約翰用網上拍賣繳交贖款，究竟唐輔這一代會明白新一代的上網心態嗎？不了解又能否替約翰低調破案？阿植又可會知道誰是真兇？以至真兇為何要陷害他嗎？　　綁匪背后真正動機又是什麼？
