An out-of-work college graduate, Jack Wilson, and his friends are transplanted-along with millions of other young adults-onto an alien dinosaur preserve, and must rapidly organize, unite survivors, and figure out how to tame prehistoric beasts to outwit rivals and survive the deadly trials of an interstellar zoo.
Earth is destroyed, but due to an oversight by an ancient alien empire, the people of Earth are saved and delivered to a nature preserve designed to save all of Earth's extinct species. The problem is that this nature preserve was set up millions of years ago, and the empire that built it is long gone. Now the remaining humans must band together to survive in a harsh environment full of prehistoric creatures. They will have to navigate the dangers of the environment and wildlife, as well as build relationships with other groups of survivors and alien observers.
