Set in the shimmering yet ruthless landscape of 1930s Hollywood, the narrative follows Herman "Mank" Mankiewicz, a brilliant, sharp-tongued screenwriter battling severe alcoholism and a broken leg after a near-fatal car crash. Confined to a remote desert bungalow in San Bernardino County in 1940, Mank is tasked with a monumental assignment: write the first draft of a controversial screenplay for wunderkind filmmaker Orson Welles within sixty days. With the help of his devoted British secretary Rita Alexander and nurse Frieda, Mank embarks on a feverish writing process that blurs the lines between his bedridden present and his tumultuous past.The plot unfolds primarily through a series of elaborate, nonlinear flashbacks that trace Mank’s trajectory through the studio system. He reflects on his warm,
complex relationship with powerful media tycoon William Randolph Hearst and his glamorous companion, actress Marion Davies, at their lavish San Simeon estate. Mank, initially welcomed into their inner circle for his wit, grows increasingly disillusioned as he watches the studio machinery exploit artists and manipulate public perception. A pivotal dramatic turning point occurs during the 1934 California gubernatorial election. Deeply disturbed, Mank watches in horror as Metro-Goldwyn-Mayer chief Louis B. Mayer and Hearst orchestrate a vicious, smear-campaign propaganda reel utilizing fake newsreels to destroy the socialist campaign of author Upton Sinclair.Mank’s fierce moral outrage is compounded by his growing disgust at how Hearst slowly compromises Marion’s burgeoning cinematic career by forcing her to star in expensive, vanity projects she does not want. Following a drunken, explosive outburst at a lavish birthday party held in Hearst's honor, Mank publicly alienates his powerful benefactors, sealing his Hollywood exile.Drawing from these deeply personal grievances and witnessing the immense corruption of the wealthy elite, Mank realizes his screenplay is much more than a contracted job for Welles—it is his ultimate artistic reckoning. He crafts a thinly veiled, scathing
character study of Hearst’s life, ambition, and tragic romance. Despite fierce pressure, threats of blacklisting, and a buyout attempt from Hearst and Mayer to suppress the script, Mank resolutely holds his ground, refusing a lucrative screen credit buyout. In the framing present, Mank finishes the sprawling manuscript, securing his legacy and setting the stage for cinematic history with the creation of *Citizen Kane*.
