Eight years after the Sona Island dinosaur escape, Dr. Alan Grant (Sam Neil Sam Neill) would never return to that hellhole. Although he took a heavy oath, the status quo had to make him withdraw his oath. One of his prehistoric animal studies was in a financial straitened situation. At this time, wealthy businessman Paul Kirby (William H. Macy) and his wife Amanda (T é a Leoni) come to Allen and invite him as a guide to take them to Sona Island for sightseeing. On the one hand, he was well paid, and on the other hand, knowing that he did not have to land on the island, Alan, who had forgotten the pain with the scar, accepted their invitation. However, things went in the opposite direction, and their plane finally made a forced landing on the island. It was only then that he learned that the Kobe couple had come here to find their missing son. At the same time, he also found that after eight years of natural evolution, the smartest dinosaur had its own language to communicate. This time his opponent is not only ferocious, but also more cunning.
