The plot, according to the official site, is this: “Anxious to fund research for his new theory of velociraptor intelligence, renowned paleontologist Dr. Alan Grant (Sam Neill) is persuaded by a wealthy adventurer (William H. Macy) and his wife (Tea Leoni) to accompany them on an aerial tour of Isla Sorna. This infamous island, once InGen’s site B, has become both a primordial breeding ground for John Hammond’s magnificent creations and a magnet for thrill-seekers eager to encounter them. When a tragic accident maroons the party of seven, Grant discovers the true reason his deceptive hosts have invited him along.”
