Op een eiland voert een team van wetenschappers een uiterst geheim klimaatexperiment uit. Een eerste poging heeft ertoe geleid dat de temperaturen enorm zijn gestegen. Een onaangename bijwerking is de gigantische groei van sommige dieren. Het eiland wemelt van de roofinsecten zo groot als huizen. Tegelijkertijd nadert het monster Godzilla. De radioactieve dinosaurus ontvangt signalen van een enorm ei met daarin zijn monsterlijke zoon. Vanaf nu moet Godzilla zijn zoon verdedigen tegen de dodelijke monsters van het eiland en natuurlijk de opvoeding overnemen. Voor de mensen te midden van de monsterlijke gebeurtenissen begint een strijd om te overleven.
Nee, helaas is 怪獣島の決戦 ゴジラの息子 nog niet beschikbaar op Netflix in Nederland.
