Zora Bennett leads a team — Duncan, Henry, Bobby, LeClerc, and Nina — to Île Saint-Hubert to collect DNA from Titanosaurus, Quetzalcoatlus, and the hybrid Distortus Rex for medical research. Meanwhile, the Delgado family — Reuben, Teresa, Isabella, Xavier — sails nearby; Y/N Delgado, the middle daughter, stays below deck, missing the evacuation as their boat capsizes.
