Two sisters living separate lives on different continents are reunited on a Mediterranean Island. The two barely have time to bond and revive family ties as Kate, the elder, meets a group of locals and agrees to an exciting ride on a hot air balloon. But disaster strikes and as the result of a freak accident, the balloon is carried far out to sea. Their cell phones out of range, and the balloon running out of gas, Kate and her friends are battling for their lives. While, back on land, the younger sister, Liz, has become an unwanted "material witness" to a crime. Matters then take a dramatic twist, one that will mark their lives forever.

 西元2274年人類居住在由電腦控制的城市中，在這個城市中無優無慮，可自由毫無拘束的追求享樂；但到30歲時每一個人必須接受考驗，一個探究永恒、重生的試煉……

　　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...
