一心想亲眼见识恐龙的达瑞斯，终于获得幸运之神的眷顾，能跟其他五个营队成员前往努布拉岛，参加一场千载难逢的冒险。

健二趁着其他成员参观基因实验室之际，偷偷带达瑞斯进入园区保密到家的黑暗地带，就这么一头栽进危险之中。

营队成员跳进自己的回转球，帮一群恐龙迁徙到新鲜的牧场。但步步逼近的暴风雨却带来意外的麻烦。

达瑞斯想起和爸爸相约的誓言。在岛屿的另一头，营队成员跟一名刚脱离控制的新面孔碰上了。

大伙跟一只帝王暴龙近距离接触后，躲进了基因实验室。一名古怪的科学家在此透露有关吴博士的真相。

森美的秘密让所有人震惊不已，但没有时间生气了。一场意外导致一群无齿翼龙脱逃，迫使成员们躲入地下。

一场惊险的追逐将大流士、肯吉和亚兹带到了老侏罗纪公园游客中心。在岛上的其他地方，布鲁克林和萨米发现了一个秘密实验室。

萨米和布鲁克林急忙向其他人警告一种新的险恶威胁，而大流士却没有意识到危险，正在搜寻他父亲最喜欢的恐龙。

当一个中毒的野营者为了生存而战斗时，他们中速度最快的亚兹必须在为时已晚之前找到解药。

现在是露营者上船逃跑的关键时刻。。。直到本消失，决定留下来。大流士能改变主意吗？

岛上到处都是威胁，恐龙爱好者大流士必须放下感情，做出艰难的决定。

当一个熟悉的面孔回到努布拉岛时，该组织被迫改变立场。现在，离开小岛不再是最重要的事情。

随着布鲁克林被囚禁，剩下的露营者想出了一个拯救她的计划——这并不容易。

营队成员来到海上享受晴空，却在船上发现不速之客。大伙遭受来自海中的突袭，幸存后发现自己被冲刷上陌生的海岸。

精疲力尽的营队成员在沙漠里躲避危险，同时试图搞清楚他们究竟身在何方，却只发现更多疑问。

大伙儿穿越诡异的隧道，来到一座蓊郁的森林，在这里遇见一位研究恐龙行为的神秘科学家。这人真的没问题吗？

营队成员在透纳博士的帮助下，想出一个离开岛上的计画。他们为此越过白雪霭霭的北极生物群落，还执行了无私的救援任务。

得知关于梅博士上司的真相后，森美打算要脱队去逮他，这时梅也准备要当面质问他。杀手机器人登场！

梅的状况岌岌可危，凯许的终极计画也逐渐明朗之际，营队成员誓言要拯救恐龙并阻止门塔企业，但是邪恶的布拉德却无所不在。

达瑞斯必须快点想办法转移凯许的注意力，才能保护其他人，于是他假装跟凯许一样厌恶恐龙，同时尽量获取情报。

达瑞斯被升级的布拉德 X 追踪，布鲁克琳必须想办法入侵系统才能拯救他。与此同时，凯许准备讨好一群危险的投资人。

达瑞斯继续用电竞转移凯许的注意力之际，其他人则闯入育婴室。雅丝问布鲁克琳对健二的感觉。

班拒绝与新朋友培养交情，之后很是后悔，但也体悟到击垮凯许的时机来临了。健二和布鲁克琳面对他们的感情。
