A H.G. Wells klasszikus sci-fi-regényéből készült film az ötvenes évek táján "divatos" marslakó-mánia egyik első terméke. Amerika lakóit állandó inváziós félelmek gyötörték (aminek reális alapja is volt: az USA és a Szovjetunio közt dúló hidegháború), erre a félelemre építve nagy mozisikereket lehetett elérni. A Világok háborúja monumentális erővel mutatja be, amint a Mars hadserege megszállja a földet.
Földönkívüliek szállnak le az amerikai hadsereg egyik bázisán. A zombikra emlékeztető lények két tudós - Dr. Russ Marvin és menyasszonya, Carol - segítségét kérik bolygójuk megmentéséhez. Ám a katonaság ágyútűzzel fogadja a csészealjakat, s az idegenek kénytelenek bosszút állni a támadásért. Képes lesz Marvin rátalálni a tökéletes fegyverre, és megoltalmazni az emberiséget?
