Jurassic Park III - Plot

Plot

Incidents surrounding Isla Sorna don't deter tourists Ben Hildebrand and Eric Kirby from para sailing around the island despite warnings, but when their boat crashes, Ben cuts them from their line and they go sailing into the wilderness.

Meanwhile, Dr. Alan Grant (Sam Neill) has become famous from his survival and reporting of his discoveries on Isla Nublar, and Ellie Sattler, never marrying Alan, is married to lawyer Mark Delger and has a son Charlie, who calls Alan "The Dinosaur Man." One afternoon, Alan's assistant Billy is able to replicate the larynx of a Velociraptor which he says indicates raptors are far more intelligent than Alan and Billy had previously been led to believe. Being approached by a couple Paul and Amanda Kirby, who offer full pay for their dig, Alan hesitantly agrees to give them a tour of Isla Sorna and Billy attends. With the Kirby's associates, Udesky, Cooper and their pilot Nash, Alan learns that they plan to land on the island. When Alan objects, he is knocked out by Cooper, only to awaken to the sound of Amanda calling out to someone on the island using a bullhorn. This attracts a Spinosaurus and Cooper manages to lead it into the path of the plane before he is devoured. The Spinosaurus then attacks the plane and manages to eat Nash while destroying the tail and sending it crashing into a tree. As they continue to escape, a Tyrannosaurus appears and the humans escape in the fray before the Spinosaurus manages to snap the T-Rex's neck. After finding Ben's remains in a para sail trapped in a tree and seeing a video of his and Eric's final descent onto the island, the Kirbys explain they're actually a divorced couple looking for their son, Eric. Their fortune is fake, and Alan's grim perspective of Eric's fate paints a sad portrait; Udesky and Grant become separated from the others when they're attacked by Velociraptors and Udesky is killed by them after being used as live bait, proving their intelligence. Alan is rescued by Eric, who has managed to survive for several weeks in an overturned supply truck, clearly impressing Alan. Eric recognizes the sound of his father's satellite phone which was lost when Nash was eaten; they're reunited with the Kirbys and Billy before the Spinosaurus attacks again. Narrowly escaping, they make their way to the site compound in the hopes of finding communications equipment, but find nothing but broken test tubes and shut down equipment.

Billy becomes possessive of his satchel, and when Alan looks he realizes Billy had taken several eggs from the raptors' nest, explaining the reason they were being attacked. Alan berates Billy for his careless behavior, comparing him to nothing more than InGen. They make their way to a large outdoor complex which turns out to be a bird cage for a Pteranodon which attacks the party and separates Eric, taking him to be eaten by their young. Billy uses the remnants of Ben's para sail and rescues Eric, shortly before he falls to an apparent death to the river below. The group finds their way out of the cage and makes their way up river using a small boat, soon retrieving the satellite phone from the deposit left by the Spinosaurus. It attacks and capsizes the boat as Alan is trying to contact Ellie, but he manages to tell her "The River, Site B" before he's disconnected. Alan and Paul manage to drive off the Spinosaurus and they start making their way toward the shoreline. Close to their goal, they're surrounded by raptors who see Amanda as a female and a threat to their clutch. Using Billy's resonant chamber replica, they manage to communicate with the raptors and Amanda returns the stolen eggs before they're startled off by the sounds of helicopters. Returning to the beach, they find that Ellie had called in the U.S. Marine Corps and the U.S. Navy to rescue them. And they discover that Billy, while critically injured, is still alive. As they depart the island, they see the Pteranodon that had escaped from their cage after the humans are now flying free, and Alan recounts that it's time for them to find their place in the world again.
