Flash Gordon: The Greatest Adventure of All

Flash Gordon arrives in World War II Warsaw as bombs rain down. A contact near death whispers a single word Mongo before dying. This word sets Flash on a quest beyond Earth.

Dale, a feisty reporter, heads toward Doctor Zarkov's lab and runs into Flash Gordon. They form an uneasy alliance as they pursue Zarkov. The encounter foreshadows their crucial roles in the mission.

The trio is bombarded by meteorites, tearing at their aircraft. They must bail out and crash-land in a hazardous landscape. Survival becomes the top priority as lava flows threaten their escape.

On the ground they discover a hidden cave that shelters them and a rocket ship that could carry them away. Hope rises as the ship is found and deemed usable. Zarkov wastes no time and pushes them aboard.

Aboard the rocket, Zarkov explains his mission to reach the wandering planet Mongo and persuade its leaders to call off their attack on Earth. He outlines a gravity-based weapon and the possibility of using force if necessary. Flash and Dale vow to help, joining the dangerous voyage.

Before contact with Mongo can be made, hostile ships shoot them down from space. The ship crashes, and the crew scrambles to survive in the unfamiliar landscape. The resolve of Flash and his companions hardens as they press onward toward their destination.

They survive an attack by two clashing dinosaurs and are captured by animalistic savages who drag them toward a giant idol for sacrifice. A narrow escape frees them into the wider hostile world of Mongo. The perilous moment strengthens their bond and resolve.

Escaping the idol, they meet King Thun of the Lion Men and assist him in fleeing from Amazonian hunters led by Princess Aura. The rescue sparks an alliance against Ming. Flash and his companions begin to see the broader resistance.

They form a coalition with Prince Barin of Arboria and King Vultan of the Hawkmen. The freedom fighters unite to oppose Ming and his mechanical army. The alliance marks a turning point in the war on Mongo.

Thun explains Ming's tactic of separate and attack, a divide-and-conquer approach. Ming has secretly provided military technology to Hitler, tying Mongo's war to Earth’s historical conflict. The revelation deepens the stakes for all involved.

Ming's Mole Men strike Arboria by destroying the fibrous roots that camouflage the forest. Zarkov's warning helps Flash and the allies repel the assault. They seize a drilling machine and use it to mount an assault on Ming's palace.

Barin insists on a trial by strength as Flash faces Ming in a dramatic duel with a flaming sword and ion blaster. Ming is revealed to be an android imposter, and the real Ming escapes. The victory is Pyrrhic, signaling the war will continue.

With only seconds before Mongo collides with Earth, Flash damages Mongo's drive on Zarkov's advice. The planet is diverted off course, averting immediate catastrophe. Flash and Dale decide there is no regret as they begin a new life on a world of wondrous adventure.
