Cricket Green, Chris Houghton, is upset that the Green family road trip will be the same as last year. He longs for something new and exciting, and his restlessness sets the tone for a story that spirals from a simple errand into a daring misadventure. When the family heads to drop off their freshly picked produce to Gwendolyn Zapp, Cheri Oteri at BigTech, Cricket stumbles upon a revelation that will change their vacation plans completely: Zapp is building a farm on an asteroid and has even erected a space hotel that only the incredibly wealthy can access.
Gwendolyn’s bold project catches Cricket’s imagination, and a spark of opportunity lights up his mind. He learns that the farm on the asteroid could be a real farm, not a mere showpiece, and that a profitable future might await those willing to travel beyond Earth. The notion tempts Cricket to strike a deal: the Greens could farm the asteroid in exchange for a free stay at the hotel, convincing Bill and the rest of the family to embark on this interstellar detour by presenting it as a harmless simulator. The family agrees under the pressure of a grand promise, and the journey into space becomes suddenly real, not just a fantasy.
As the ship doors close and the blackness of space looms, danger escalates quickly. Bill Green, Bob Joles, nearly gets sucked into the void, and his life hangs in the balance until a dutiful astronaut, Colleen Voyd, Renée Elise Goldsberry, intervenes and pulls him back from the edge. The moment is jarring and galvanizing: the joke of a pretend trip dissolves into a high-stakes mission among the stars. Meanwhile, Tilly Green, Marieve Herington, forms an unlikely bond with a small, gooey creature that can crack glass, a friendly nuisance she baptizes as Cookie. The discovery of this peculiar companion brings moments of light to an otherwise perilous odyssey, softening the tension with-childlike wonder.
Cricket’s triumph in bargaining with Zapp collides with a deeper conflict at home. Gramma Alice, Artemis Pebdani, and Cricket briefly clash as Voyd’s presence is perceived as an obstacle to their fun, prompting the pair to trap Voyd in a cryo-pod. The action on the asteroid intensifies when the Greens arrive to face off against the farm bots, the robotic guardians meant to enforce Zapp’s plan. Tilly and Alice respond with quick thinking and courage, releasing Voyd in hopes of regaining control. Yet Voyd’s arrival triggers a chain of events that ripples through the whole operation: she uses the only escape pod to send some of the harvested produce back to Earth to satisfy Zapp’s orders, revealing the true stakes behind the dream of a space-farm paradise.
The melodies of optimism begin to falter as the crew learns there is a way to shut down the rogue robots, but the method requires reaching an energy compound at the far end of the asteroid. The journey to secure that safeguard is fraught with danger, and when the compound is destroyed, the farm silos explode in a catastrophic failure that buckles the asteroid out of its orbit. As the ship lurches and the landscape of space becomes a sea of stars and danger, Cricket and Bill are pulled into a fierce disagreement about the mission, the purpose of their voyage, and the future of their family, a rift that seems to threaten their bond just as surely as the asteroid’s peril.
From Earth, the Greens’ antics play out on the national news, drawing attention from Nancy Green and Gloria Sato, who head toward BigTech to demand answers. Nancy Green, Wendi McLendon-Covey, and Gloria Sato, Anna Akana, uncover a maze of corporate interest, hidden motives, and a plan that stretches far beyond a single family’s vacation. As the truth unfolds, Zapp’s motives come into sharper focus: her dream to farm in space springs from a personal hunger to prove the skeptics wrong, a spiteful need to outdo her Kindergarten teacher Mrs. Kay, Barbara Goodson, who once dismissed her ambitions as mere fantasy. The revelation casts a new light on Zapp’s ambitions and the consequences of pursuing a dream at any cost.
With the asteroid hurtling toward Earth, the group must improvise a recovery. Nancy and Gloria join forces to broadcast a rescue signal, coordinating a plan to contact everyone on board the ship using Gramma Alice’s mechanical leg, and the Greens rally around Voyd as a surprising ally. Cracks in the team begin to close as Cricket and Bill begin to reconcile, recognizing that their best chance to save everyone lies in working together rather than competing for control. The rescue plan pivots on the space hotel’s tractor beam, a powerful tool that can seize the asteroid and pull it back toward safety.
Remy Remington, Zeno Robinson, lends a hand in this pivotal act, guiding a coordinated escape where guests sprint toward the available escape pods in a bid to survive. The moment crystallizes into a vital teamwork montage: Cricket and Bill combine their wits to reenergize the tractor beam, while Voyd, freed from the cryo-pod, redirects the escape lines and helps shepherd the party to safety. As the tension peaks, Tilly lends a final, symbolic gesture by gifting Cookie to Voyd, a small creature that has become a symbol of resilience and friendship, and the group collectively makes their final, desperate push to safety.
The space hotel reels under the strain of the rescue operation but does not fail. The ship gradually regains control, the asteroid becomes a navigable object once more, and the guests descend into escape pods just as the hotel buckles and shatters. The Greens, along with their allies, survive the ordeal, and though their vacation has turned extraordinary, they choose to continue exploring the vastness of space, letting the stars be a canvas for their renewed family bond. The escape pod sequence feels like a release of fear, a moment where celebration and relief intermingle as they drift away toward an uncertain but hopeful horizon.
As the credits roll, the story threads resolve in ways that reinforce the film’s central message: ambition can be dazzling, but it gains meaning when paired with responsibility and compassion. Gwendolyn Zapp’s arc ends on a note of public reaction—she’s booed for abandoning Earth in pursuit of a solitary dream—yet Voyd rises, becoming the captain of the BigTech space fleet, a testament to collaboration and resilience. The Greens’ voyage may have begun as a family vacation that went off-script, but it finishes as a reminder that adventures are better shared, with every member contributing to a broader, brighter future among the stars.
