Brantley Foster, played by Michael J. Fox, is a determined young graduate who has just completed his business degree in the heart of Kansas. Eager to embark on his professional journey, he relocates to the bustling streets of New York City to start an entry-level position at a prominent investment firm that he secured while still a student. However, upon arrival at his new workplace, he comes to a shocking revelation: the firm is on the brink of shutting down due to a hostile takeover, leaving Briantley and 90% of his fellow employees without a job. Despite this setback, Brantley's spirit remains unbroken as he continues to seek new opportunities. Unfortunately, he faces a string of rejections, with interviewers frequently informing him that he lacks the necessary experience to land a position.
Determined to turn his luck around, Brantley decides to leverage a family connection he never knew he had. His mother had mentioned that he is related to Howard Prescott, a distant uncle and the esteemed CEO of Pemrose, one of the wealthiest investment firms in the world. With a spark of hope, Brantley makes his way to Howard’s office, using his resourcefulness to convince Prescott's secretary to grant him a brief meeting with the executive. Impressed by Brantley's unconventional approach—including creating a business card featuring his own smiling face—Howard takes a chance on him and offers him a position in the mailroom.
In this new role, Brantley, who is unwelcome in the mailroom itself, quickly aligns himself with another employee, John Pankow as the free-spirited Fred Melrose. Fred coaches Brantley on how to navigate the daily grind of delivering mail while still making time for bit of mischief. He also shares insights about the company, allowing Brantley to become familiar with Pemrose's operations through confidential memos and documents. One day, Brantley’s fortunes take an unexpected turn when he finds himself behind the wheel of a limousine, transporting the irritable executive Vera, played by Margaret Whitton, back to her opulent home after her vehicle breaks down. During their ride, Brantley’s infectious charm wins Vera over, leading to an invitation for a drink at her luxurious estate, where they share a revealing conversation about her troubled marriage.
The progression of their relationship takes a surprising twist, culminating in a romantic encounter that could open doors for Brantley within the company. However, just as he begins to envision his future, his world crumbles when he learns that Vera's husband is none other than his uncle, Howard Prescott. Overwhelmed with embarrassment about the secret affair, Brantley makes a hasty retreat from Vera’s estate, fearing he has tarnished his family's name.
Back in the mailroom, opportunities arise as Brantley overhears valuable information about changes occurring in Pemrose. A stroke of luck occurs when he manages to resolve shipping issues afflicting an important client, which garners attention from the executives. Inspired, he seizes the moment and adopts a new persona: Carlton Whitfield, stepping into the shoes of an executive whose departure leaves a vacant office. But his ruse is not without risks; his behavior begins to draw suspicion from his mailroom supervisor and the tension rises.
Brantley’s world becomes even more complicated when he encounters the alluring Christy Wells, played by Helen Slater, during a high-level management meeting. Initially dismissing Brantley, Christy’s attitude gradually shifts as she recognizes his insight and ambition, particularly regarding the impending takeover bid by Donald Davenport, a powerful figure played by Fred Gwynne. During a heated meeting, Brantley suggests that aggressive expansion might protect Pemrose from a takeover, although his proposal is quickly tanked as staff dismiss him as too youthful.
As Christy finds herself embroiled in an affair with Howard Prescott, she is tasked with monitoring Brantley, further complicating their budding connection. Yet, during a chance encounter while both work late at the office, they find common ground and a spark ignites, leading to an intimate night filled with passionate discussions that solidify their bond.
With an important retreat scheduled at Howard’s estate, the stage is set for chaos as all parties converge, including a suspicious Vera who wants to keep an eye on Brantley. As events unfold, miscommunication and secrets come to light, revealing Brantley’s true identity. The consequences are dire—both Brantley and Christy are dismissed from Pemrose, but they find solace in their relationship, which deepens amid the turmoil.
In a climactic twist, Brantley and Christy courageously confront Howard and Donald Davenport during a key executive meeting, announcing a plan that will not only protect Pemrose but also involve a merger that paves the way for a newly redefined corporate structure. Their united front gains favor, especially after Vera steps in to confront Howard, unceremoniously firing him and taking control of the company she has a stake in.
Their victory celebrated, Brantley and Christy embark on a new chapter of their lives, but not before taking a glamorous trip to the Metropolitan Opera in a limousine driven by Brantley’s former boss, setting the stage for yet another adventure in their bright new future. Each character's journey exemplifies the complexities of ambition, relationship dynamics, and the relentless pursuit of success in the high-stakes world of finance.
