As December 1958 dawns in New York City, Norville Barnes, portrayed by Paul Newman, arrives on the vibrant streets of Manhattan, eager to establish himself in the cutthroat corporate landscape. Unfortunately, his inexperience lands him in the role of a mailroom clerk at Hudsucker Industries, a massive corporation where his ambitions seem a distant dream.
Disaster strikes when the company's founder, Waring Hudsucker, meets an abrupt end by jumping from a top-floor window during a tense meeting. Following this tragedy, Sidney J. Mussburger, played by Tim Robbins, a cunning board member, seizes the moment to exploit the situation for personal gain.
While struggling with his new mailroom duties, Norville is asked to deliver a cryptic "Blue Letter" to Mussburger. Instead, he opts to showcase his simplistic invention—a drawing of a circle accompanied by the phrase, "you know: for kids." Mussburger, misjudging Norville's capabilities, appoints him as a figurehead for Hudsucker, unwittingly setting off a series of events that will redefine the company's future.
In pursuit of the truth behind Norville's surprising ascent, Amy Archer, a fearless Pulitzer Prize-winning reporter portrayed by Jennifer Jason Leigh, takes on a disguise to shadow his rise. She manages to become Norville's personal secretary, aiming to reveal the secrets of his success while discovering the quirky clock tower operator, Moses. Their clandestine exchanges reveal Mussburger's devious plan to manipulate stock values and gain control over Hudsucker Industries.
Yet, Norville's meteoric rise is challenged when his invention—the hula-hoop—becomes a phenomenal hit. As he revels in newfound fame, Amy observes with increasing concern as his initial humility transforms into arrogance, compelling her to end their relationship. Simultaneously, Buzz, the cheerful elevator operator, introduces a new invention—the "Buzz-sucker," a bendy straw. However, Norville's disdain for creativity leads him to unceremoniously fire Buzz, rejecting his pleas for support.
As New Year's Eve approaches, a series of events spiral out of control. Aloysius, a modest janitor, accidentally reveals Amy's true identity to the manipulative Mussburger, who strategically convinces the board that Norville is unfit to lead and should be institutionalized, clearing a path for his own rise to power.
Overwhelmed with guilt, Amy seeks out Norville, only to find him despondent and intoxicated in a beatnik hangout. Despite her apologies, he storms out, pursued by an enraged Buzz. Norville escapes to the rooftop of the Hudsucker skyscraper, where Aloysius awaits to trap him. Just as the clock strikes midnight, he finds himself teetering on the ledge, narrowly saved by Moses, who freezes time within the giant clock.
In this peculiar moment, Waring Hudsucker's spirit appears, guiding Norville to uncover the Blue Letter from his pocket—a document outlining the former mogul's wishes for passing on his shares to a worthy successor. This profound insight unravels Mussburger's intricate web of deceit and instills in Norville a new understanding of his predicament.
As tension escalates in the clock's inner workings, Moses triumphs against Aloysius. When time resumes, Norville safely returns to ground level, where Amy is eager for reconciliation. In the ensuing months, Mussburger's machinations fall apart as he faces dire consequences, while Norville finds peace in developing yet another invention—a folded paper circle that takes flight as a frisbee, delighting children around the globe.
