Rex Simpson, Emma Roberts, is a Florida party girl with a secret fascination for space. A gifted amateur inventor who earned a full scholarship to Georgia Tech, she left college after her mother’s death to take care of her father, and she now works as a bartender and even performs as an alligator wrestler. Her contrast between a vibrant, carefree life and an earnest dream about the stars sets the tone for a story that blends grit with whimsy.
At a ten-year high school reunion, Rex reconnects with Toddrick Spencer, a billionaire who made his fortune in space tourism, Sebastián Yatra. Toddrick reveals that Rex was one of his inspirations, and the spark of possibility rekindles in her. Motivated to chase her dream, she chooses to apply to NASA to become an astronaut. There’s one problem: she doesn’t meet most of the conventional requirements, and her best friend Nadine, Poppy Liu, steps in with a bold plan—she embellishes Rex’s résumé and quietly pushes her toward a life-changing opportunity at the Johnson Space Center.
As Rex begins training, the path is rocky. Her outfits and easygoing demeanor raise eyebrows among the other candidates, and an introductory interview with the NASA board exposes the truth behind Nadine’s deception. Yet Rex manages to salvage the situation, keeping her secret mostly intact as she hides the magnitude of the lie from most people. The tension intensifies when Rex’s roommate, Violet, Kuhoo Verma, accidentally uncovers the ruse. The two form a pact: Violet will help Rex catch up academically, while Rex helps Violet become physically prepared for the demanding program. Rex’s genuine talent and determination begin to win over many of the other hopefuls and even the program directors, including Pam Proctor, Gabrielle Union, and Logan O’Leary, Tom Hopper.
Meanwhile, Nadine’s scheme relies on a web of fake references—voicemails, Google reconnaissance, and an office soundboard—that keeps the ruse afloat for a time. Rex’s progress earns her some respect, but the deception remains a fragile pillar beneath the surface. The group bonds deepen as Rex and her cohort navigate the grueling schedule, and a late-night karaoke outing culminates in a planetarium gathering where Rex and Logan share a charged moment that hints at their evolving relationship.
As the training culminates, the final test arrives: a two-week Mars habitat simulation. Rex performs admirably, and when flight training resumes the next day, Nadine’s courage falters as the truth cracks open. A video call slips through a crack, exposing Rex’s falsified credentials, and the situation explodes. Although Rex manages to land the simulated craft under pressure, she is expelled from the program, and her dreams of an astronaut career seem dashed.
Ten months pass. Rex returns to her ordinary life, but her former fellow trainees head toward the International Space Station. A meteorite shower causes debris to lodge in a crucial airlock, trapping the astronauts inside. Facing a race against time, Rex—along with Violet—takes the helm of a rescue mission using Toddrick Spencer’s spacecraft. Rex’s unconventional thinking and quick, calm decision-making enable her to devise a solution to free the crew and bring everyone home safely.
In the epilogue, Rex reveals the new chapter of her life: she and Violet have become astronauts for Toddrick Spencer’s company, they’ve launched a “space camp” to inspire young girls, Nadine remains part of their unconventional circle, and Rex has begun a relationship with Logan. The story closes on a note of growth, resilience, and an unconventional path to the stars, with Rex embracing a future where imagination and perseverance push beyond the boundaries she once thought defined her.
