An unknown entity has decided to eradicate mankind due to its capacity of violence.

At the end of the Korean War, United States Air Force pilot Hal Jordan and his wingman, Kyle "Ace" Morgan, are attacked by enemy pilots but survive. In Gotham, J'onn J'onzz - the last survivor of the Green Martian race - is teleported to Earth; unable to return, J'onn disguises himself. In Las Vegas, Iris West is on the telephone with her fiancé Barry Allen - also known as the Flash - at a casino when Captain Cold arrives to commit robbery; he races from Central City to confront Cold. Flash finds the five bombs hidden by Cold and captures him, before Cold is possessed by an entity.

After two years, J'onn (as John Jones) is a detective with the Gotham City Police Department. A doomsday cult that worships the "Centre" has kidnapped a child for a sacrificial ritual; J'onn and his partner Slam Bradley join Batman in battling the cult, but a fire renders J'onn powerless. The cult leader is possessed by the entity, who identifies itself as the "Centre", and warns of impending judgement. Hal trains under Col. Rick Flag at Ferris Aircraft for a U.S. government project, as explained by Carol Ferris, to build a spacecraft for travel to Mars. Special agent King Faraday oversees the project.

Batman suggests to J'onn that they work together in investigating the Centre-worshiping cult. The Flash defeats a robotic duplicate of Gorilla Grodd; after being targeted by the government, he announces his retirement. J'onn interrogates former Ferris employee Harry Leiter, apprehended for murder while under The Centre's influence, who tells them about the launch to Mars and when Faraday arrives, J'onn briefly glimpses into his mind to learn the truth. Seeing the contemptuous response to the Flash's announcement, J'onn gives his research to Batman and plans to hide on the rocket. J'onn and Faraday fight on the launchpad; the rocket is damaged and malfunctions after leaving Earth's atmosphere. Hal wants to attempt a landing but Flag reveals weapons of mass destruction are on board, intended to destroy any life on Mars. Hal is ejected from the cockpit and saved by Superman; Flag detonates the rocket as J'onn is held prisoner.

On Paradise Island, Wonder Woman trains with Mala before being attacked by The Centre. After crash-landing on Earth as a result of Flag's rocket explosion, a fatally wounded Abin Sur gives his ring to Hal and tells him of The Centre, which is described as a monstrous creature that seeks the destruction of humans; Sur dies shortly after, despite Jordan's efforts to save him. Superman and Batman review J'onn's research as Lois Lane reports that a giant pterodactyl is attacking Cape Canaveral. Wonder Woman's invisible jet crashes and she warns that The Centre is coming. J'onn decides to help save Earth after his hope for humanity is renewed. The Centre, a massive flying island with an army of mutant dinosaurs to guard it, begins its attack on America, the Flash, Green Arrow, Adam Strange, the Challengers of the Unknown, and the Blackhawks work with the soldiers on the base; Superman engages the Centre but is defeated. Moved by his efforts, the heroes plan to use Ray Palmer's reduction ray to destabilize the island along with a frontal assault while Hal and Ace fly a bombing mission into the creature, leaving Flash to crisscross the island with the ray.

The aerial assault is nearly outmatched and a herd of dinosaurs ambush Faraday's ground forces, the Centre's psychic force briefly overwhelms J'onn. Faraday is captured by a dinosaur and both perish after Faraday sets off hand grenades. Hal and Ace shoot their way into The Centre's core but a hallucinogenic attack disorients them; a thick red fluid jams their weapons and almost suffocates them. Hal's ring relays instructions from the Guardians of the Universe on its use. Ace detonates his payload before Hal rescues him. The Flash races across the ocean, leaps onto The Centre's surface and covers it on foot, the Centre begins to shrink; Hal envelops the island in green energy, towing it into space where it explodes. As the team celebrates their victory a glowing light emerges from the water and Aquaman emerges from a submarine carrying Superman.

The world celebrates the Centre's defeat with a ceremony. The film ends with a montage of various heroes and villains, including the birth of the Justice League set to the titular John F. Kennedy speech.
