The Lost World: Jurassic Park

Four years after the events on Isla Nublar, a British family anchors their yacht off a beach on Isla Sorna and comes ashore, unaware of the genetically engineered dinosaurs on the island. Their daughter, Cathy Bowman, wanders off and is attacked by a pack of Compsognathus but survives the encounter.
Peter Ludlow, nephew of Dr. John Hammond, uses the incident to oust Hammond and gain control of InGen. The company's second facility, "Site B" on Isla Sorna, was where the dinosaurs were cloned before moving them to the park in Nublar, but the island was abandoned during a hurricane several years earlier. Ludlow plans to exploit Isla Sorna's dinosaurs to save InGen, prompting Hammond to request Dr. Ian Malcolm's help in documenting the creatures to promote a non-interference policy. Ian's girlfriend, paleontologist Dr. Sarah Harding, is already on Isla Sorna, leading Ian to reluctantly agree to go, but only to retrieve her. Ian travels to Isla Sorna with equipment specialist and engineer Eddie Carr and video documentarian and activist Nick Van Owen. They find Sarah and discover that Ian's daughter Kelly has stowed away in their research trailer. Ludlow and a mercenary team arrive on the island to capture dinosaurs, with help from big-game hunters Roland Tembo and Ajay Sidhu.
Ian's group realizes that Ludlow intends to ship the captured specimens to San Diego for a new Jurassic Park, using a nearly finished amphitheater that Hammond abandoned in favor of the Isla Nublar site. Nick and Sarah free the captured dinosaurs, and the animals wreak havoc on the InGen team's camp. On the way back to the trailer, Nick rescues an injured Tyrannosaurus rex infant that Roland used as bait to hunt its father. Knowing this will bring the baby's parents to them, Ian takes Kelly to safety and returns to the trailer to warn Sarah and Nick. They successfully treat the infant, but the parents arrive, having tracked the infant's scent. The adult Tyrannosaurs reclaim their infant and destroy the trailer by overturning and pushing it partially over the cliff before leaving the area. Eddie arrives with a rope to rescue them and attempts to pull the trailer back up with his SUV, but the engine noise attracts the attention of both Tyrannosaur adults again, where they tear Eddie's SUV apart, and devour him.
Ian, Sarah, and Nick are rescued by Ludlow's team and forced to work together since both groups lost all their communication equipment in separate attacks. They decide to travel to an abandoned InGen base to call for help. After the team sets up a camp, they are ambushed by the Tyrannosaurus adults, who were led to the camp by the scent of the infant tyrannosaurus' blood on Sarah's jacket. The party flees into a field of long grass where a pack of Velociraptors ambush them, killing Ajay and most of the team. Ian's group reaches the InGen base, fights off the Velociraptors, and successfully radios for helicopter extraction. Nick reveals that he stole Roland's bullets to prevent him from killing his trophy. However, Roland has sedated the male Tyrannosaurus with tranquilizers. As InGen personnel arrive to secure the male and infant, Roland declines Ludlow's job offer at the San Diego park, reflecting on Ajay's death and the morality of Ludlow's scheme.
At the Port of San Diego, Ian and Sarah attempt to convince Ludlow to abandon his plans, but the ship carrying the male Tyrannosaurus suddenly crashes into the docks. The crew is found dead, and the adult is accidentally released and rampages throughout the city. Ian and Sarah locate the infant at the planned park and use it to lure the adult back into the cargo hold of the ship that brought him. Ludlow tries to retrieve the infant but the male incapacitates him and gives him to the infant to be its first kill. Sarah uses a tranquilizer gun to sedate the male and Ian closes the hold's doors.
In the aftermath, the dinosaurs are shipped back to Isla Sorna accompanied by the U.S. Navy. Ian, Sarah, and Kelly watch Hammond in a televised interview announcing that the American and Costa Rican governments have declared the island a nature reserve. The Rex family is seen reunited, with the parents grazing with their infant in an open field.
