Summary
Arco Dorell is a ten-year-old boy in the year 2932, an idyllic future where humans live in the clouds and travel through time using rainbow flight suits. Arco, too young to fly, steals his sister's time-traveling cape and gemstone in the night and attempts to travel to the distant past to see dinosaurs. In the year 2075, robots perform most essential jobs and extreme weather events and wildfires are commonplace, though most infrastructure is protected by bubble-like barriers activated during such events. Ten-year-old Iris and her infant brother Peter are looked after by a kindly robot caretaker named Mikki while their parents spend the weekdays working in the city. Iris and her neighbor Clifford bike to school through debris from the previous night's violent storm, unfazed by the wreckage. Excusing herself from class to sit outside and draw, Iris sees a rainbow speeding through the sky. She follows it to its end and discovers Arco crash landed in the forest. Three eccentric brothers named Dougie, Stewie, and Frankie encounter Iris in the forest and seem to be looking for Arco. Iris sends the brothers in the wrong direction, but they find the gemstone from Arco's suit. Iris takes Arco back to her home, where Mikki tends to Arco's wounds and mends his cape. Arco and Iris bond. Arco tells Iris about how future humans have moved into the clouds to allow the Earth to rest and Iris sketches the design of the platform homes from his description. The three brothers are tracking Arco. Arco explains that he cannot fly without the gemstone unless it's raining and sunny at the same time, which rarely happens. Mikki, unaware that Arco is from the future, calls the police in a well-meaning attempt to reunite him with his parents. Iris and Arco escape to her school to evade the police, while a massive wildfire rages over the town. Clifford sees Iris and Arco leave the house and follows them, as do the three brothers. Mikki shows up at the school with Peter, but the police robots at the scene will not allow them to enter. The three brothers confront Arco and Iris but ultimately prove amiable and help them evade the police. They return the gem to Arco and he attempts to fly home from the roof of the school, but Iris begs to come along. As the wildfire grows stronger, a bubble barrier begins to enclose the school. Arco escapes to the outside of the barrier. Iris, assisted by Clifford despite him not wanting her to go, narrowly joins Arco on the outside of the barrier before it closes. Arco agrees to take Iris with him, but their combined weight is too heavy and they crash into the middle of the burning forest. With Peter in tow, Mikki follows the rainbow trail from Arco's flight, finding Arco and Iris unconscious amid the wildfire. Mikki tries to carry them to safety out of the forest, but falling trees force them to shelter in a cave. Iris wakes up safe in an underground area with Arco and Peter. She finds Mikki carving detailed images of its memories into the cave wall, including one of Iris and Arco flying with a rainbow trail. When Mikki turns to face Iris, she sees it is badly damaged and on the verge of breaking down. As it dies, Mikki tells Iris to leave it and go. Iris escapes from the cave with Arco and Peter. When they reach the outside, many rainbows descend upon them. Arco immediately realizes his family has come to his rescue, but is surprised to find his parents are now elderly and his sister is an older adult. Arco's family explains that they have spent their entire lives searching through time for Arco and finally found him thanks to the cave art Mikki made. Iris and Arco say goodbye before he leaves with his family. It is hinted that Iris becomes an architect and designs the platform homes of the future, as well as beginning to invent time travel.
