Daly is the Chief Technology Officer of a tech company. Together with his old friend Walton, he founded Callister Inc. and developed the virtual reality game "Infinity Loop." By simply attaching a chip to the temple, players can escape the real world and immerse themselves in exploring a virtual universe of planets, making the game immensely popular. However, Daly is inherently timid and has been treated by Walton as a cash cow, while other employees in the company don’t take him seriously. He has few friends, and his greatest passion is collecting memorabilia from the old TV series Space Fleet. This decades-old sci-fi show featured many forward-thinking designs that deeply fascinated Daly. The company’s name is derived from a spaceship in the series, and Infinity Loop is also built on the blueprint of this show.
Day after day, Daly is ignored in his own company until a programmer named Nanette joins the team. Nanette admires the programming algorithms behind Infinity Loop so much that she quit her previous job specifically to join Daly’s Callister Inc. For the first time, receiving admiration from the opposite sex leaves Daly flustered, and he develops a secret crush on Nanette. Yet, too timid to speak to her, he conceives a twisted idea.
Suddenly, Nanette finds herself waking up inside a spaceship. Through the window, she sees the vast universe outside. Panicked, she runs around and accidentally stumbles onto the bridge, realizing she is not alone. On the bridge are CEO Walton, receptionist Elena, intern Parker, tester Dudani, and HR manager Lori. Like her, they are dressed in strange uniforms, and Elena even has blue skin. Through their explanations, Nanette comes to understand that all of this is Daly’s doing.
This spaceship is the Callister, a privately customized version of Infinity Loop that Daly built on a server at home. Here, Daly holds supreme control. The others are digital DNA clones—replicas created from biological samples Daly collected from people in the real world. Unlike in reality, on this ship, they must obey Captain Daly’s commands and endlessly praise his brilliance and wisdom.
Nanette is horrified that someone would replicate people into a game and torment them over trivial matters. She runs out of the bridge searching for an escape but finds her entire body emitting a golden light. When the light fades, she reappears on the bridge’s transporter, with Daly smiling down at her. Unaware of Daly’s power, Nanette refuses to play along with his cruel game. In Daly’s world, he can alter anything with a snap of his fingers. For her defiance, Daly makes Nanette lose her facial features—condemning her to eternal suffocation, unable to die, trapped in endless agony.
Forced into submission, Nanette becomes a member of the crew. This time, they are accompanying Daly to a planet to battle the antagonist Valdak. As Valdak’s alien beetles charge menacingly toward them, Daly’s communicator rings—his pizza delivery has arrived. Daly pauses the game and returns to the real world to answer the door. Nanette notices that everything freezes: Daly stands motionless, the crew rests in place, and even the alien beetles retract their claws. She overhears Walton greeting one of the beetles—it’s actually Gillian from marketing, transformed into a repulsive alien beetle for refusing to cooperate.
Once Daly returns, fed and refreshed, the game resumes exactly where it left off, playing out the farce of the captain’s inevitable victory. After basking in the crew’s praises, Daly logs off, satisfied, and everyone breathes a sigh of relief. As digital beings, they don’t need sleep, food, or water. While Walton idly bangs his head out of boredom, Nanette begins plotting their escape.
Even the smartest programmers leave loopholes, and Nanette is determined to find one. After a night of effort, she finally accesses the game’s interface through the ship’s computer. The interface has an "invite a friend" feature—the only way to communicate with the outside world. The invitation is limited to 140 characters. Nanette briefly explains the situation and sends the digital invitation to the real Nanette’s phone. Unfortunately, the real Nanette mistakes it for a game invitation from Daly. After checking with him, she dismisses it as spam, unaware of the plight of her digital counterpart. This oversight costs them dearly: Lori is turned into an alien beetle for pleading on Nanette’s behalf. The terrified expression on Nanette’s face gives Daly a twisted sense of satisfaction.
In despair, Nanette leans against the window, tears streaming as she gazes into the endless cosmos, fearing she may be trapped forever on this ship. Suddenly, a wormhole flashes in the distance—a sign of a game update patch interface, as she knows from experience. After confirming with tester Dudani, she learns it’s a Christmas Eve update patch. Seeing this rare chance to connect with the outside world, Nanette forms a plan. Flying the ship into the wormhole would crash it into the firewall, which would delete all illegal programs, including the unauthorized digital clones. Rather than suffer eternally, she prefers to seek release through death.
But it’s not that simple. First, this is Daly’s private server—the ship can only move when Daly is in the game. Second, Daly keeps collected DNA samples in a fridge by his bed; even if they succeed in dying, he can always resurrect them. After much thought, Nanette devises a comprehensive plan.
The next time Daly logs in, Nanette acts charming and affectionate, even requesting to accompany the captain on a solo mission. Their task is to investigate a crashed shuttle. When they reach a lake, Nanette strips off her uniform and swims to seduce Daly. Having never interacted intimately with a woman, Daly is easily tempted. He removes his uniform, leaving his communicator on it, and joins her in the water. Meanwhile, Dudani on the ship beams the communicator back, uses its external connection to access the real internet, downloads provocative photos from Nanette’s cloud account, and sends a blackmail email before quickly returning the communicator.
On Christmas Eve, while working overtime at the company to check the update patch, the real Nanette is shocked to receive her own provocative photos. To prevent them from leaking, she follows the "hacker’s" instructions and sneaks onto Daly’s balcony. She first orders a pizza to be delivered. When Daly leaves the game to answer the door, she enters his bedroom, steals all the DNA samples from the fridge, and swaps the game chip on his desk with a fake one. Meanwhile, the digital Nanette transports back to the ship during the pause and accelerates full speed toward the wormhole.
The fake chip doesn’t buy much time. Daly quickly replaces it with a backup and logs back into the game. Noticing Nanette’s disappearance and the ship’s disconnection, he realizes something is wrong. He jumps into the crashed shuttle, repairs it in seconds, and chases after the Callister. Aboard the Callister, Nanette and the others navigate through an asteroid belt, plunge into the wormhole, and cheerfully embrace their impending death. But after several flashes, they find themselves unharmed. Their strange uniforms have changed into standard game attire, and even Elena’s blue skin returns to normal.
It seems the firewall has deleted Daly’s unauthorized rogue programs while preserving the compliant ones. Nanette, Walton, Parker, Elena, and the restored Lori can now explore the endless universe within the game and communicate with other players in the real world. As for Daly, his privileged programs are erased. Trapped in his own game, he drifts forever in the dark cosmos—a fitting punishment for his actions.
