12-year-old Mike Goldwing is not just any kid; he comes from a legacy of NASA astronauts, with both his father and grandfather having ventured into space. However, his grandfather, Frank Goldwing, now lives a life filled with regret, having been estranged from the family after losing his chance to participate in the Apollo 11 moon landing.
Enter Richard Carson III, a billionaire from Texas who harbors ambitious plans of claiming the Moon as his own, intent on mining its rich Helium-3 resources. To further his agenda, Carson spreads a false narrative suggesting that the historic moon landing was staged. With ambitions sky-high, he devises a scheme to travel to the Moon and eliminate the evidence—the American flag placed there by the Apollo 11 team.
In this high-stakes environment, the President of the United States tasks NASA with planning a new mission to the Moon to thwart Carson's underhanded ambitions. However, the billionaire grows desperate and employs a saboteur to undermine NASA’s efforts.
Inspired to take action, Mike sneaks aboard the spacecraft to join the mission. Alongside his friends Marty and Amy, and Marty's companion, the pet iguana Igor, they embark on a daring journey to the Moon. But things take a wild turn when Marty is caught in a marsh down by Kennedy Space Center, fighting off alligators while trying to avoid detection.
When Carson’s henchman triggers an early launch, Mike, Amy, Igor, and Frank find themselves rocketing off to the Moon, with the troublesome billionaire hot on their trail. Upon arrival, the adventurous trio manages to retrieve the iconic flag. With ingenuity, Amy connects her phone camera to the spacecraft's antenna just as Carson reveals his nefarious intentions, broadcasting his plan for all to see.
The plot thickens as Mike realizes that even if Carson returns to Earth, his victory would still loom large. Thus, they devise a plan to sabotage Carson's elaborate Helium-3 mining facilities. Furthermore, Mike learns the painful backstory behind his grandfather's absence in the Apollo 11 mission—Frank had contracted chickenpox from his son, Scott, which caused him to miss the historic flight. Initially blaming Scott for his misfortune, Frank eventually comes to terms with his own failures and recognizes the unfairness of his previous resentment.
Epic chases ensue as Mike, Amy, and Igor evade Carson by riding on makeshift surfboards crafted from rocket parts down the rocky cliffs of the Moon. They ultimately orchestrate the destruction of Carson's operation using Marty's communication rocket, surviving the ensuing explosion.
In a heartwarming conclusion, they return to Earth with the flag in tow and Mike's hopes of reuniting his family intact. Grandfather Frank reconciles with his family, acknowledging his past mistakes. The triumphant trio is celebrated as heroes, paving the way for a new chapter in their lives, while Amy basks in the glory of being recognized as the first woman to land on the Moon.
