Hi . I'm elio solis! *At the camp, Elio escapes from Bryce, Caleb, and two other bullies who try to scare him one night. At the military base, Olga receives strange space messages in response to Elio. While Elio is being bullied, a spaceship arrives and kidnaps him. Inside the spaceship, he meets a liquid supercomputer named OOOOO and is accepted into the Communiverse, where aliens share information from their worlds. The other ambassadors mistakenly declare him as an ambassador to Earth, thinking he created the Voyager spacecraft. Before Elio can explain, they attend an emergency meeting with Lord Grigon, a disowned warlord who threatens to take over the Communiverse by force. The ambassadors plan to return Elio to Earth, but Elio chooses to negotiate with Grigon for his immediate appointment as ambassador. OOOOO creates a clone of Elio to take his place on Earth. Olga brings Other Elio home from camp after hearing about the previous fight.

Meanwhile, Elio attempts to negotiate with Grigon, but ends up imprisoning him after unintentionally angering him. While trying to escape prison, he encounters Grigon's son Glordon, and decides to use him as a bargaining chip to ensure Grigon leaves the Communiverse alone. They return to the Communiverse, and Grigon agrees to leave them alone in exchange for Glordon's safe return.

Elio and Glordon trust each other; Elio feels lonely and misunderstood by his aunt, while Glordon resists becoming a war machine like his father. Elio devises a cloning plan to keep them together. He puts the real Glordon in an escape shuttle and gives the fake one to Grigon. Grigon notices the change immediately and uses Questa's mind-reading powers to find them. While Grigon sends soldiers to find his son, Questa, upset by Elio's deception, sends him back home to escape Grigon. In the meantime, Glordon accidentally activates the shuttle and heads towards Earth.

When he returns home, Elio is devastated, but soon sees his aunt on the beach with Other Elio, who has been searching for her, suspecting that Other Elio is not his real nephew. After making up, they sneak to the military base where Elio's shuttle is being taken under control. While Other Elio sacrifices himself to distract the soldiers, Elio and Olga sneak into the base and find Glordon dying in the shuttle. They seek out Bryce and Melmac to take him back to the Communiverse to avoid space debris.

When they return to the Communiverse, they take Glordon to his father, who tears his clothes to swaddle him, saving his life. Grigon apologizes to his son and the ambassadors, while Elio returns to the Communiverse. Elio declines, telling him that Earth is his home and bidding him farewell. Questa reminds him that he is never alone before sending him and Olga home. Elio and Bryce then continue to communicate with Glordon via a radio.*
