Grant learns that the Kirbys are a middle-class, divorced couple who are looking for their son Eric and Amanda's boyfriend Ben, who are missing on the island. The group finds the parasail attached to Ben's corpse. They take the parasail and then encounter raptor nests, and find an abandoned InGen compound. A raptor chases them and summons the rest of its pack. The humans flee into a herd of Corythosaurus and Parasaurolophus, causing a stampede, and separating Grant and Udesky from the others. Raptors attack Udesky in an attempt to lure the others out of a tree. The raptors almost capture Amanda when she tries to descend to help Udesky. The raptors' trap fails and they kill Udesky before departing.
