Eight years have passed since the dinosaurs escaped from Isla Sorna, and Dr. Alan Grant (Sam Neill) is unwilling to return to that haunted place. Although he made a solemn vow, the current situation forced him to retract his vow. His research on prehistoric animals was in a financial dilemma.

On the one hand, the reward was quite good, and on the other hand, he learned that he didn't need to land on the island. Alan, who had forgotten the pain after the scar healed, accepted their invitation. However, things went in the opposite direction, and their plane finally made an emergency landing on the island.
