Doraemon: Nobita and the Windmasters

The film opens with a televised report about a herd of flamingos mysteriously disappearing. Nobita wakes from the footage and becomes determined to fly on his own. He builds wooden wings after Doraemon refuses to help, setting off a string of failed attempts to take to the sky.

A portal splits open in the clouds and a humanoid bird riding an airplane steps through, catching everyone by surprise. He introduces himself as Gusuke from a distant world called Birdopia. Doraemon, Nobita, and Shizuka decide to help him repair his aircraft, sparking a new friendship.

Doraemon, Nobita, and Shizuka pledge to help Gusuke fix his aircraft, and a budding friendship forms. They realize they may have to venture into a strange world if they want to reunite him with Birdopia. The mission tightens the group's cooperation as they prepare for the journey ahead.

Gian and Suneo spot Gusuke's aircraft and seize the plane, prompting a chase through the portal into Birdopia. The chase pulls Nobita and friends into a new world with unfamiliar skies and dangers. The group follows to rescue Gusuke and retrieve the aircraft.

Gian and Suneo are swiftly captured by crow soldiers and brought before the vulture Commander Seagrid, who dreams of executing them. Seagrid reveals his bitterness toward humans and his intent to wake Phoenicia to doom humanity. Meanwhile, Doraemon, Nobita, and Shizuka slip away with Gusuke's help to avoid capture.

Doraemon, Nobita, and Shizuka hide from their pursuers and find Gusuke near Owl Professor Hou’s house after fleeing with an ostrich taxi. Hou explains that Birdopia is a world far from the human realm, connected only during bird migrations and guarded by the Bird Migration Patrol Troops. Seagrid, a fallen former member, seeks vengeance after a human wound, hoping to awaken Phoenicia.

To survive, Doraemon brings special Bird Hats that sprout wings when worn, turning him into a pigeon, Nobita into a duck, and Shizuka into a swan. The trio and Gusuke use the hats to hide from captors and to mount a daring rescue of Gian and Suneo. After the rescue, Gusuke’s group are outfitted with new hats modeled on an albatross and a woodpecker.

Gusuke reveals that there will be an annual event called Rally Icarus, a recruitment rite for the Patrol Troops, and urges Nobita and friends to join. During a dinner with Gusuke’s adoptive family and his friend Milk, he confesses that he is adopted and cannot fly naturally due to trauma from a past fall. The group bonds over his vulnerability and resolves to help him.

Hou deciphers an ancient tablet that hints at Phoenicia, a dragon-like ancient being capable of destroying the world. The crow captain reports this to Seagrid, who then abducts Hou to locate Phoenicia and enact his plan to destroy humanity. Doraemon and friends monitor the situation while preparing for an imminent crisis.

At Rally Icarus, Gusuke wins the competition but is disqualified when Babylon enforces a rule against those who rely on machines to fly. The group learns Hou is missing and sets out to locate Phoenicia and prevent Seagrid from unleashing it. Doraemon uses Translator Jelly to read the tablet and identifies Icarus as a legendary eagle imprisoned in Birdopia's prison.

Icarus agrees to help stop Seagrid from awakening Phoenicia, and the team travels toward a frozen mountain where Phoenicia lies dormant. A holographic projector reveals Mamoru Torino, a 23rd-century ornithologist who once dreamed of a safe haven for birds and helped build Birdopia. The group presses on, hoping to reach Phoenicia before it awakens.

The party arrives too late; alarm has sounded and Phoenicia is waking. Doraemon tries to de-evolve Phoenicia into an amoeba using his Transgression Beam, but a misfire instead makes Phoenicia evolve into a larger form. Phoenicia’s rampage tests everyone’s resolve, and Gusuke finds renewed courage to fly.

Icarus’s encouragement helps Gusuke discover his own flight power, and he uses it to lure Phoenicia toward the Perched Tree where the final confrontation looms. Doraemon and Nobita ascend to the tree’s summit to reach Mamoru Torino’s time machine and plan their final strike. The team coordinates to neutralize Phoenicia once and for all.

Doraemon seizes the time machine and casts Phoenicia billions of years into the Pre-Hadean Era, stopping the cataclysmic danger. The world reels from the abrupt intervention, but Birdopia and Earth begin to heal from the ordeal. The heroes reflect on how a voyage bridged two very different realms.

With Phoenicia contained and Birdopia safe, Shizuka returns home with her canary while Nobita and the others return to their own world. They carry memories of a remarkable voyage that connected two realms and taught them about courage, friendship, and responsibility. The two worlds are forever linked by the adventure they shared.
