Amy's car plunges off the Golden Gate Bridge, but our heroes suspect it was no accident-- more like, Richard has abducted her. Kong, Lukas, Jonesy, Danny and Panchi fly off to rescue her and soon, despite false leads and traps set by Richard and Botila, they return to Kong Island, break into the lab, find Amy, and escape.
After Commissioner Decker fails to find Kong in the redwoods, Richard transfers the reluctant Botila's consciousness into a T-Rex body to create the ultimate fighting (and deforestation) machine and lure the ape out. As Kong contends against Botila-Zilla, Richard and Lukas have a showdown at their old family home.
Deep in a mountainous African jungle, Lukas and the kids hunt for the missing Kong, torn between wanting to find him and hoping their big beautiful friend discovers the family and roots he went searching for. Kong does find a small troop of apes, but so do Richard and company - along with a lot more than anyone bargained for, including a lost world of REAL dinosaurs.
