Jurassic Park III

Four years after the second film, The Lost World, Alan Grant (Sam Neill) and Ellie Sattler (Laura Dern) have continued their paleontological careers but are working independently now; Ellie is married with two children, and Grant is still digging with his protégé Billy Brennan (Alessandro Nivola). He is approached by Paul (William H. Macy) and Amanda Kirby (Téa Leoni), saying they are wealthy thrill-seekers who want Grant to be their guide on an aerial tour of Isla Sorna. Grant is reluctant at first, but the Kirbys' promise of funding his dig gets the better of him.

Grant suspects that something is not quite right when the plane carrying him, Billy, the Kirbys, and some mercenaries lands. After Amanda uses a megaphone to try to call out to someone in the jungle, they are attacked by a Spinosaurus, which later saves them from a T. rex. As they attempt to escape in the plane, they accidentally run into the Spinosaurus and crash, resulting in the deaths of two of the mercenaries, and stranding them on the island. Grant finds out that the Kirbys are actually searching for their son, Eric (Trevor Morgan), who was stranded on the island in a paragliding accident. He decides to lead them to the coast, increasing their chances of getting rescued. Along the way, they spot the paraglider, but without Eric. Billy salvages the paraglider, and Grant discovers several nearby nests of Velociraptor eggs.

The group then explores the abandoned InGen compound, where they are attacked by a Velociraptor. When they flee, they get ambushed by its fellow raptors, resulting in the death of the final mercenary. When Grant becomes separated, he is rescued from several raptors by young Eric Kirby, who has been living on the island for 8 weeks in the back of an abandoned water truck. Eric has taken supplies and food from the InGen compound and has salvaged other tools for survival. When the group reunites, but they are attacked again by the Spinosaurus. After they find shelter in another building, Grant finds out that Billy has stolen two Velociraptor eggs. He is furious with Billy, claiming that he is "no better than the people that built this place".

To reach a boat docked in a nearby river, the group must pass through a massive aviary where they are attacked by numerous Pteranodon. Using the paraglider he salvaged, Billy tries to rescue Eric from a nest of Pteranodon chicks, but is attacked by several adults, seemingly killing him. Grant and the Kirbys board the boat, and while floating down river, they hear a phone ringing, finding several mounds of dung containing a satellite phone the Spinosaurus had eaten from the plane. Grant attempts to contact Ellie, but only gets out "The river... Site B! The river!".

The group is close to the shore when the raptors reappear, wanting their eggs back. The eggs are given back to the raptors, and they retreat when they hear the approach of helicopters. They arrive at the beach to see a military detachment, no doubt sent by Ellie. As they board a helicopter, Grant finds Billy, still alive but badly injured. He tells Grant that he has "rescued" his hat, to which Grant jokingly replys "that's the important thing."
