Kong, you may remember, is dwelling in Hollow Earth; Godzilla is napping at the Colosseum. As long as they’re in separate corners, everything is OK.
Godzilla, however, gets up from his nap, stomps around Europe (making even more ruins in Italy and France) and senses there’s a Kong-frontation just waiting to happen.
Kong, meanwhile, has an infected tooth and needs help. We know this because Dr. Ilene Andrews (Rebecca Hall) has a daughter (Kaylee Hottle) who can communicate with him via sign language. To set things straight, Andrews assembles a crew (including a conspiracy theorist and a gonzo veterinarian) and zips to Hollow Earth. Sure enough, Kong has a bad bite and another set of monster adversaries. When a battle hurts his arm, the vet (played by Dan Stevens) cooks up a Kong-sized Infinity Gauntlet glove (trademark pending) and gets the big ape moving.
All sorts of creatures (prehistoric and otherwise) start checking in. The goal is to settle them and get to Godzilla. But who first? And when?
