John Hammond did not perform miracles: he simply combined business with the achievements of science. He invested in relic DNA research, bought an island off the coast of Costa Rica and created a unique biological park. Real, living dinosaurs are kept there in conditions close to their native Jurassic period. The businessman is confident that the project will be a great success! This should be confirmed by scientific experts whom Hammond invited to the park before the official opening. His grandchildren - Lex and Tim - will also take part in the first excursion to the world of dinosaurs... Who could have imagined that a combination of circumstances would turn an entertaining trip into a disaster?!
