Four years after the Jurassic Park disaster, everything seemed to be back to normal: John Hangwen’s international genetic technology company was close to bankruptcy, and Nubra Island was listed as a restricted area. However, John Hangwen has a little secret that is not humane: There is a larger dinosaur manufacturing factory on another island. That island is called Saona Island, which is the B area of the International Genetic Technology Corporation. More importantly: Jurassic Park is destroyed, but the dinosaurs are still on earth.
A British family accidentally landed on Sanda Island. Their daughter not only discovered the Serognathus on the island, but was also attacked and injured. This incident reached the ears of Dr. Sarah and John who landed on Nubra Island. John Hangwen intends to organize a research team to return to Saona Island to study the ecology of dinosaurs, and to confirm the animal behavior theory of tyrannosaurus family affection. And invited Dr. Ian to join the team. Ian was rejected the most, but when he learned that his girlfriend had been sent to the island, he was willing to join the team. The purpose is to save his girlfriend, and John uses satellite images as evidence to prove that dangerous carnivorous dinosaurs live in the inner periphery of the island. In theory, as long as you stay on the periphery, you can avoid being attacked. He arrived at Sana Island with all the team members, but when they arrived, they realized that someone had already made the first step. The company that used huge bribes to bribe computer engineers in Jurassic Park came to the island to hunt live dinosaurs and shipped them back to the capital of Costa Rica to build another Jurassic Park. Their biggest goal is an adult tyrannosaurus. In order to achieve their goal, they first capture a juvenile tyrannosaurus and lead the adult tyrannosaurus into a trap.
The expedition researching the ecology of dinosaurs rescued the juvenile tyrannosaurus, but was mistaken by the adult tyrannosaurus for harming the cubs. The equipment of the expedition was completely destroyed and many people were killed. The survivors started a big escape, and some of the survivors were ambushed by the Velociraptor because they strayed into the grass. When they left the island by helicopter, they found that the company's operation had been successful, and they used a freighter to transport the Tyrannosaurus back to the city. The Tyrannosaurus was in trouble during the transportation, killing the people on the ship, and the freighter crashed into the urban area under unmanned conditions. The Tyrannosaurus escaped, causing a earth-shattering battle in the urban area.
