In 1961, the catastrophic Bay of Pigs invasion leaves a lingering shadow. Senior CIA officer Edward Wilson is alerted to rumors of a suspected "mole" within his ranks. Upon returning home, he stumbles upon a picture of a man and woman entwined in bed, alongside altered audio tapes that obscure key truths.
Reflecting back to 1939, we find Wilson at Yale University, where he is invited to become a member of the exclusive Skull and Bones fraternity. During this initiation, he reveals the existence of a suicide note penned by his father, Thomas, an admiral whose loyalty was questioned, preventing him from ascending to the position of Secretary of the Navy.
The plot thickens when FBI agent Sam Murach recruits Wilson to scrutinize his poetry professor, Frederick, rumored to have Nazi sympathies. After he is outed, Frederick resigns. Soon, Wilson becomes romantically involved with Laura, a fellow Yale student who cannot hear. As the outbreak of World War II becomes imminent in Europe, Laura proposes intimacy but halts at the last moment.
In 1940, a social gathering introduces Wilson to Margaret "Clover" Russell, sister of fellow Bonesman John. He also meets General Bill Sullivan, who informs him that the U.S. will need to enter the war, offering Wilson a role within foreign intelligence. Captivated by Clover’s aggressive allure, despite her family's isolationist background, Wilson finds himself unable to resist her advances.
As tensions rise, Wilson has a fateful encounter with John, who reveals that Clover is pregnant, suggesting responsibility falls upon Wilson to marry her. This revelation leads Laura, who reads their lips, to walk away in despair. On the day of Wilson and Clover's wedding, he receives orders to report to London.
Upon arrival in London, Wilson reunites with Dr. Fredericks, a covert British intelligence operative who initially recommended him for counter-espionage training. Here, Arch Cummings of the Special Operations Executive warns Wilson that Fredericks poses a security risk due to his indiscreet relationships and ultimately meets a tragic end through assassination when he refuses to cooperate.
In the post-war chaos of Berlin, Wilson collaborates with a Soviet agent known as "Ulysses" during the exchange of captured scientists. In a twist of fate, he learns from a phone call that Clover is unfaithful. A brief affair with his interpreter, Hanna Schiller, ends tragically when he discovers she is also a Soviet operative, resulting in her death.
By 1946, Wilson returns to a colder home, where Clover resumes her birth name, Margaret. Each confesses to infidelities, including the sorrowful news of John's demise in war. General Sullivan approaches once more, this time to aid in the formation of the CIA alongside colleague Richard Hayes, under the directorship of Phillip Allen.
Despite the genuine bond he shares with his son, Edward Jr., Wilson finds Margaret's growing discontent due to his work-first attitude increasingly unbearable. A high-ranking KGB defector, Valentin Mironov, presents concerning intelligence about "Ulysses," warning of others impersonating him seeking refuge. In an unexpected reunion at a play, Wilson reconnects with Laura, sparking an affair that ends when Margaret discovers incriminating photographs and confronts him publicly.
Chaos ensues when another defector challenges the reputation of Mironov, revealing deep layers of deception and double agents. During a nightmarish interrogation, Mironov manages to escape by launching himself out a window, while others get ensnared in this web of deceit, including Edward Jr.
As Edward Jr. follows in his father’s footsteps to Yale, he expresses an interest in the CIA, prompting an emotional confrontation between him and Wilson where he admits he married Margaret begrudgingly, merely out of obligation. When relations with Cuba destabilize due to Fidel Castro's rise, Edward Jr. learns of the Bay of Pigs operation, instilling concern in Wilson over his son's silence and Margaret's decision to leave him.
In 1961, after the Bay of Pigs debacle, the CIA meticulously analyzes the dubious recordings entrusted to Wilson. An investigation in Léopoldville, Congo, uncovers unsettling truths about his son. When "Ulysses" presents an unfiltered recording with Edward Jr. disclosing critical information to his girlfriend, Miriam, the stakes escalate, leading to tragedy when she is ultimately assassinated, unbeknownst to Wilson.
As Edward processes the chaos, he visits the new CIA headquarters, where he contemplates the Biblical inscription that decorates the lobby: "And ye shall know the truth, and the truth shall make you free (John 8:32)." Meanwhile, internal corruption comes to light with Philip Allen's disgraceful resignation following embezzlement revelations. Newly appointed Hayes promotes Wilson to head the CIA's counter-intelligence operations, contemplating the deeper implications of agency identity.
In a poignant conclusion, Wilson finally decides to confront his father’s suicide note, which confesses betrayal and pleads for forgiveness, while urging Wilson to live with integrity. As he prepares to step into his role in the newly established counter-intelligence division, Wilson burns the note, signifying a tumultuous, yet transformative chapter in his life.
