Jake finds himself in a perplexing situation when he wakes up in a hotel room to a reality that he cannot grasp. Next to him lies a dead body, and he is accompanied by a suitcase brimming with cash. Battling a painful bruise on his head, his memory is a complete blank. As he exits the hotel, he encounters a woman named Diane, who claims to be his wife and kindly offers a ride out of the hotel. However, their departure is soon interrupted by the arrival of FBI agents, who begin to piece together the chaotic events that transpired.
Diane insists on taking Jake to a grand mansion, which she claims is their home. Yet, as Jake surveys the place, he becomes increasingly skeptical, noting his absence from any family photographs. In a twist of fate, Diane attempts to seduce him while probing for information about a mysterious computer chip he allegedly acquired at the hotel. Struggling to recall his past, Jake experiences fragmented memories hinting at a life involving firearms and high-stakes military operations. When a doctor suggests administering Sodium Pentothal to him, Jake, feeling alarmed, escapes the mansion with his suitcase in tow.
While enjoying lunch at a local restaurant, Jake encounters a waitress named Gina, who seems to know more about his life than he does. She gives him an unexpected revelation—that he is not the super-spy he imagines himself to be, but merely a janitor at a nearby video game company named DART. Meanwhile, Diane informs Hauck, DART's head, that Jake is a janitor who has intruded on their security and stolen a crucial computer chip belonging to the company. Hauck quickly adds that time is of the essence to retrieve the chip.
Confusion surrounding Jake's identity mounts when Gina takes him back to her place, unveiling a janitor's uniform that he apparently wears. Jake talks about his past, recalling vague memories of being Colonel Bowman of the Special Forces. Eventually, he receives a call from Riley, who instructs him to meet at the airport. When he arrives, Riley presses Jake for the whereabouts of the X-1 computer chip, linking him to Boca Raton. Suddenly, their conversation is shattered by agents led by Shaw who erupt onto the scene, leading to an intense firefight that captures Jake while Gina attempts to follow.
During his captivity, Shaw administers Sodium Pentothal to Jake while Diane interrogates him about the chip’s location. Amidst the chaos, Jake experiences a flashback and manages to escape with Gina in her car. In a startling revelation, Gina confides in Jake that she is a Federal agent too, defying her superior Martin’s orders to turn herself in. Gina vows to gather incriminating evidence against Shaw in order to clear her name.
In a nod to their circumstances, Jake takes Gina to a video game store, where they discover that Colonel Bowman is indeed a character in Jake's favorite game. They soon realize that the X-1 chip is capable of transferring information without detection and has lucrative value on the black market. With Jake's newfound focus, he explains to Gina that “Boca Raton” translates to “mouth of the rat,” leading them to search a building where they discover the chip hidden in a rat figurine in a video game room. However, their discovery triggers yet another clash with the FBI agents who had pursued them earlier.
In a moment of clarity, Jake recalls a crucial piece of the puzzle: two FBI agents had once offered him a suitcase filled with money in exchange for the computer chip, which ended in a deadly confrontation. Drawing on his instincts as a former janitor, Jake and Gina harness their janitorial tools to outmaneuver the pursuing agents and confront Hauck. Finally, Jake fully embraces his identity, acknowledging that he is indeed just a janitor after all.
In the end, Martin expresses gratitude towards Jake and offers him a place in the FBI training program; however, Jake opts to pursue a career as a video game developer under Riley's guidance instead. As they make their exit, Gina hints at deepening their relationship, while Jake carries away the suitcase of money, ushering in a new chapter in their lives.
