Five years after the events of Jurassic World Dominion, there are few dinosaurs left on Earth living in equatorial regions where the climate resembles that of yesteryear. The three largest creatures in this tropical biosphere hold in their DNA the key to manufacturing a drug that will bring great medicinal benefits to the human race. Zora Bennett, an expert in covert operations, is hired to lead a team of specialists whose mission is to obtain the genetic material, but the members of the operation end up on a forbidden island where a secret Jurassic Park research center was located years ago. There, in a place populated by dinosaurs of numerous species, they will face a discovery as surprising as sinister that has been hidden for decades.
