Nausicaä of the Valley of the Wind
The story takes place 1,000 years after the "Seven Days of Fire", an event which destroyed human civilization and most of the Earth's original ecosystem. Scattered human settlements survive, isolated from one another by the Sea of Decay (腐海, fukai?). Literally translating as the Rotting Sea, Sea of Fungus, Sea of Corruption or Toxic jungle in the English version, the Sea of Decay is a jungle of giant plants and fungi swarming with giant insects, which seem to come together only to wage war. Everything in the Sea of Decay, including the air, is lethally toxic.
The primary protagonist, Nausicaä, is a charismatic young princess of the peaceful Valley of the Wind. Her name comes from the princess Nausicaa in the Odyssey who assisted Odysseus, and is transcribed into Japanese as ナウシカ, pronounced [naɯɕika]. In English, the Greek name is normally pronounced /nɒˈsɪkeɪə/, but in the soundtrack for the film it is /ˈnɔːsɨkə/. Part of her character comes from a Japanese folk hero known as "the princess who loved insects", while another part was inspired by the writings of Bernard Evslin, as he had written a more in-depth extrapolation of character of Odyssey's Nausicaa. 
Although a skillful fighter, Miyazaki's Nausicaä is humane and peace-loving. She has an unusual gift for communicating with the giant insects (particularly with the Ohmu, the gigantic, armored, caterpillar-like insects who are the most intelligent creatures in the Sea of Decay). She is also noted for her empathy toward animals, humans, and other beings. An intelligent girl, and inspired by the mentor figure Yupa, a wandering samurai type possessed of great wisdom, Nausicaä frequently explores the Sea of Decay and conducts scientific experiments in an attempt to define the true nature and origins of the toxic world in which she lives. Her explorations are facilitated by her skill at "windriding"; flying with an advanced glider-like craft with a jet assist called a möwe. Yupa is searching for the mythological man in blue who, according to the legend, will appear surrounded by a sea of gold and reunite the people and nature.
One day, an airship (a kind of large cargo airplane) crashes onto the cliffs near the Valley of the Wind. Nausicaä tries to rescue a hand-cuffed girl of her age from the burning wreck, but she dies after telling that she is Princess Lastelle from the kingdom Pejite and that the cargo of the airship must be destroyed. The airship is from Tolmekia and the cargo turns out to be a God Warrior (kyoshinhei embryo, Giant Warrior in the English version), one of the lethal, giant, biological weapons used in the ancient war.
It is later revealed that the God Warrior embryo was unearthed by Pejite, but it was stolen by the more powerful state of Tolmekia (Tormekia in the manga). While transporting the Warrior back to their realm, the Tolmekians were attacked by insects and subsequently crash-land in the Valley. The very next day, the Tolmekians, under the leadership of princess Kushana, invade the Valley to kill the Valley king and to secure and revive the Warrior. Kushana explains that the God Warrior will be used to burn the Sea of Decay, although Obaba, an old and blind Valley woman warns that attempting so will only enrage the Ohmu and lead to more deaths.
Kushana attempts to return to Tolmekia, with Nausicaä and several others as hostages. Before their departure, Nausicaä reveals to Yupa a hidden garden of jungle plants, that are not toxic because they are growing in sand and water from a deep well. Nausicaä explains that the jungle is only toxic due to the toxic soil that is everywhere on the surface of the earth. The airships with Kushana and Nausicaä are attacked by a Pejitan gunship and several of the ships are forced to make an emergency landing in the Sea of Decay. There, Nausicaä communicates with several ohmus and discovers that the pilot of the Pejitan gunship is still alive. With the help of her glider, Nausicaä rescues the pilot from a swarm of enraged insects. However, they crash and end up in a strange, non-toxic world that is below the Sea of Decay; the plants in the Sea of Decay purify the polluted soil, and in this way produce clean water and sand, which remains hidden in this underground world. The pilot turns out to be Asbel of Pejite, the twin brother of princess Lastelle.
Nausicaä and Asbel return to Pejite, which turns out to be destroyed after the Pejite people lured the insects from the Sea of Decay into their town in order to kill the occupying Tolmekian forces. The Pejite people reveal that they will do the same thing to the Valley of the Winds in order to recapture the God Warrior. To prevent Nausicaä from alerting the Tolmekians, they capture her, but she escapes with the help of Asbel. With a gunship, she returns to the Valley, but along the way they encounter a enormous herd of enraged Ohmus who are on their way towards an injured baby Ohmu, which is used by the Pejite people to lure the Ohmus to the Valley. Nausicaä releases the baby ohmu and gains its trust.
In the meantime, the Tolmekians try stopping the herd with armored vehicles they brought with them but to no effect, later Kushana arrives with the God Warrior to stop the ohmu herd, but the Warrior, woken too early, dies in the process. However, Nausicaä, with the baby ohmu, is finally able to stop the ohmu herd, but she is overrun and slain in the process. In front of the Valley people and the Tolmekian forces, the ohmus use their gold-colored tentacles to revive Nausicaä, whose dress has turned blue by the baby ohmu's blood; thus Nausicaä turns out to be the mythological "man" in blue mentioned in the beginning. The film ends with fragments of a future where people and insects live in peace with each other.
The story holds deeper meaning than its depiction of war; there are both humanistic and ecological subtexts in Miyazaki's narrative. Even the insects seem to be working toward some secret harmony and the lethal fungal forest seems to have a vital role in Earth's new ecosystem.
