Griffin Mill, expertly portrayed by Tim Robbins, is a high-powered studio executive firmly entrenched in the cutthroat world of Hollywood. Dating story editor Bonnie Sherow, played by Cynthia Stevenson, Griffin's life revolves around filtering through an enormous slush pile of screenplays, ultimately green-lighting a mere 12 projects out of a staggering 50,000 submissions each year. However, his seemingly sturdy position becomes precarious with the arrival of a rising star in the industry, Larry Levy, who is portrayed by Peter Gallagher and serves as a reminder of Griffin’s diminishing control.
Tension escalates dramatically as Griffin begins to receive a series of menacing postcards, which are assumed to be from an embittered screenwriter whose pitch Griffin had rejected. He believes this writer to be David Kahane, acted by Vincent D'Onofrio, and becomes obsessed with uncovering the truth. In an uncharacteristic display of desperation, he decides to stalk Kahane, coming across June Gudmundsdottir, played by Greta Scacchi, who unwittingly provides Griffin with the whereabouts of her boyfriend.
Under the guise of a chance meeting, Griffin approaches Kahane at a screening of The Bicycle Thief, hoping to entice him with a profitable script deal. Following an evening of drinking at a bar, tensions flare as Kahane, realizing Griffin's dishonesty, confronts him about his lack of integrity, leading to a brutal fight in the bar's parking lot. The conflict takes a tragic turn when Griffin, feeling threatened, fatally injures Kahane, orchestrating the scene to appear as though a robbery had gone awry.
The morning after this harrowing incident, Griffin receives yet another postcard, piquing both his paranoia and guilt. Attending Kahane’s funeral, he forms an unexpected bond with June, who stands apart from the rest of the mourners. Meanwhile, Walter Stuckel, the studio’s chief of security, confronts Griffin about his connection to the murder, raising suspicions among detectives Avery and DeLongpre, played by Whoopi Goldberg and Lyle Lovett, respectively. As they delve deeper into the investigation, Griffin's life spirals into a precarious game of cat and mouse with law enforcement.
In a twisted turn of fate, Griffin feels a burgeoning romance with June, igniting a passion that he had resisted for too long. With Bonnie away on business in New York, they enjoy the glitz of a Hollywood awards banquet, further cementing their relationship. However, under the looming threat of Larry Levy’s growing influence at the studio, Griffin orchestrates a plan to sabotage the film Habeas Corpus, believing that if he allows it to underperform, he can reclaim his dominance at the studio.
As their affair intensifies, Griffin must confront the mounting pressures of his double life: as a murderer and a devoted partner. When police interest heightens again following crucial information from an eyewitness, Griffin narrowly avoids capture when the witness fails to identify him. One year later, a revamped version of Habeas Corpus featuring a new, optimistic ending represents Griffin's successful manipulation of the situation, positioning him as head of the studio. With his marital status shifted to that of a husband to June—now pregnant with their child—Griffin faces one final twist when the elusive postcard writer reveals himself, pitching a story about a studio executive who kills a writer and evades justice. Recognizing this for what it truly is—blackmail—Griffin reluctantly agrees to the deal, leading to the film's ironic title: The Player.
