Naga tends to become Garuda's food. A man discovers that he has been transported into a rainbow, three-head Naga body named Sawette (which means white) with some part of the former owner of the body's memory. Just as he is getting used to his Naga form, exploring his underwater cave habitat, catching fish, and eating it on the water’s surface, he is captured by a Garuda. but as Sawette is coming to terms with death, a Garuda named Sahasrangsi (which means sunlight) intervenes and captures him instead.

Sawette inquires Sahasrangsi about things he's curious about, things like why a Garuda has to eat a Naga. Luckily, Sahasrangsi doesn't eat Naga like other Garudas. He just wants to save Sawette's life, he drops Sawette off afterward but Sawette is starving and can't remember his way home. Therefore, Sahasrangsi has to take Sawette back to Chim Phli Palace, the Garuda's habitat. He tells Sawette to shapeshift into his human form and intends to give Sawette a lift home later.

There are plenty of Garudas living in Chim Phli Palace, Sawette sees a seven-headed Naga driving a chariot. That Naga is Indrayudh, a fellow rainbow Naga like Sawette. It seems that Indrayudh and Sahasrangsi don’t get along much, they end up fighting each other until Sawette has to stop them. That night, Sawette transforms back into his Naga form at the Chim Phli Palace as Naga will undeliberately shapeshift back into their Naga form while asleep. Chaos stirs because the Garudas there want to eat Sawette.

Wanetai, the Garuda King, calls Sawette and Sahasrangsi to inquire about the commotion. But then, Sawette accidentally lights Wanetai's palace on fire so Wanetai threatens to have Sawette for his next meal. The Naga begs the Garuda King that he has never seen heaven and the Himmapan Forest, Sawette appeals to visit these places before he dies. Wanetai grants his wish and sends Sahasrangsi to escort and keep an eye on the Naga.

As he travels to each place, Sawette has some issues about being a Naga, his muscle feels sore all over when he has to sleep in the Naga form. Even though other Nagas don't seem to have that problem. At the Himmapan Forest, Sawette makes friends with Indrayudh and other magical creatures in the Himmapan like a Gandharva, a musician celestial being, Kraisornsingha, a white lion, Hayra, a half dragon and half Naga creature, and a tiny little green Naga. The Naga even gets involved in the Holy War, a battle between the Deva (gods) and Asura (demons). Sawette meets Lord Indra, King of gods and ruler of Tavatimsa heaven. The Naga tries to ask Lord Indra to grant his wish of forbidding the Garudas to prey on the Naga but Lord Indra cannot grant that wish.

As time passes, Sawette still determines to make Garuda and Naga live together in harmony, even though the path of achieving that goal is still far ahead of him. Eventually, Lord Indra blesses Sawette with the ability to maintain his human form while asleep. The Naga no longer has to transform back into a Naga form and makes his back sore while he sleeps ever again. Sawette starts to see the pros of being a Naga at last.
