Grace Bennet is an ornithologist from Maryland who, with 3 other researchers, were given the chance to go to the island of Avetoro for researching the unique Caribbean birds, but only she and another left. Now, two years later, she is drafted onto a team to investigate the disappearances.

However, the team was slaughtered and left only Grace and Adam Butch, a mercenary, alive on an island of dinosaurs. Possibly the last ones alive, they need to get off or die as well.
