Jurassic Park 3

Dr. Alan Grant (Sam Neill) was personally shaken by his encounter with live dinosaurs, but he remains determined to study them. Desperate to fund research for a new theory about velociraptor intelligence, he's particularly vulnerable when the wealthy Kirbys approach him, offering money for his presence on an aerial tour of Isla Sorna, adjacent to Isla Nublar, the site of Grant's nightmarish experiences. Once fate causes them to crash on the island, he learns that it was a scam concocted by the Kirbys to get an experienced guide to help them find and rescue their son, who vanished while vacationing... not realizing that Grant's prior visit was NOT to Isla Sorna. Marooned in a savage land, they have to struggle to escape from all sorts of new creatures with their lives.
