Two paleontologists, Alan Grant and Ellie Sattler, were financed by John Hammond, a very wealthy man. The two were visited by a man named Morris who was very interested about Hammond. Apparently he had leased an island off the west coast of Costa Rica for some type of big development that had been in the making for some 10 years. Part of the plan was to buy large quantities of amber, which drew attention from Morris, because amber was of little or no value. Shortly after the visit the two paleontologists were called by Hammond to come visit his island. He told them it was a type of biological preserve that he believed would alter all science across the world.
Hammond needed them to come look at his island to give him their opinions about weather the island was safe for business. Hammond said the island would be called Jurassic Park. During the development of the island word spread of the new finding to a rival company. Dodgson, who worked with the company knew that he knew Hammond was on to something big and he wanted a part of it.
He arranged to met with one of Hammond’s employees, Nedry. At the park he was in charge of design of the park’s computer system. Nedry informed Dodgson that they were recreating dinosaur embryos but wasn’t sure how. Nedry agreed to steal embryos from the park in exchange for $1 million. In the meantime Sattler and Grant arrived at the island where they met friends of Hammond’s, including Ian Malcolm, a famous mathematician. The others were Dennis Nedry; Henry Wu, the brains behind the park; and Ed Regis, a lawyer.
Later Hammond’s grandchildren arrived, Lex and Tim. When all had arrived and were settled the tour began. It consisted of six people: Hammond’s grandchildren, Malcom, Dr. Sattler and Dr. Grant, and Ed Regis.
While on the tour it was explained how the dinosaurs were created. First amber that had hardened millions of years ago with mosquitoes or other blood drinking bugs. DNA was extracted from the blood and was used to recreate dinosaur embryos. There were 15 different species and 238 individual dinosaurs.
During the tour weather became bad weather. Because of the bad weather all power went out and without Nedry, who was quietly stealing embryos, it could not be fixed. However, Nedry was killed by a dinosaur because of a wrong turn. But back at the park the system could not be fixed, but Arnold, a computer programmer thought by rebooting the system it would work, but this had never been done before. However, while the power was out all of the dinosaurs got loose and ran loose around the park. All the people on the tour were stranded and had to make their way back to the main building through the park.
On their way they found eggs of the dinosaurs which proved that no matter how well something is planned something can always go wrong. After arriving in the control room Grant was told to go to the power room and turn the power back on manually and he did so. After all power had been restored to the park the reaming survivors, Muldoon, Tim, Lex, Grant, Sattler, and a few workmen, board a helicopter and abandoned the island.
