On the morning of December 21, 1970, the legendary actor and singer Elvis Presley arrives at the White House, urgently seeking a meeting with President Richard Nixon. His extraordinary request? To be sworn in as an undercover agent for the Bureau of Narcotics and Dangerous Drugs. Interestingly, the government had begun recording all presidential communications from February 1971, meaning this remarkable meeting remains undocumented.
The day starts off like any other for Nixon, yet he is irked by the idea of meeting with Elvis and is keen to find out who arranged such a bizarre encounter. Meanwhile, Elvis, feeling trapped in Memphis, plans a quick trip to Los Angeles. He encounters trouble at the Memphis airport due to carrying firearms. A crisis calls for a solution, and he reaches out to his longtime friend, Jerry Schilling. Jerry advises him to charm the authorities with a photo opportunity, which successfully gets Elvis out of his predicament.
Amidst his woes, Elvis proposes starting a studio to Jerry, who isn't interested. However, Elvis expresses a more pressing concern: he believes the United States is deteriorating due to rampant crime, warfare, and civil unrest, and is earnest about wanting a federal badge to help make a difference. Soon after, the two head to Washington D.C., where Elvis hand-delivers a letter to the White House requesting his audience with the President. This sparks excitement among the White House staff who see Elvis as a means to validate Nixon’s image, especially since he is beloved by southern voters.
As Elvis waits nervously in a hotel room, White House executives discuss the implications of meeting with a pop culture icon. The debate rages on, hinged on the fact that Elvis holds immense popularity among a significant voting block. However, Elvis, undeterred, ventures to the Department of Narcotics and Drugs to connect with J. Edgar Hoover. There, he discusses his worries about drug abuse affecting American youth with [John Finlator](Tracy Letts), the Deputy Director, who ultimately dismisses Elvis's proposal.
Meanwhile, Jerry gets a promising call from [Egil Krogh](Colin Hanks) of the White House press department, hinting that the meeting with the President may soon be finalized. He proposes the idea to Nixon, who hesitantly considers it but initially prefers to avoid the “rock star” in his office. However, the determination of Nixon’s daughter, Julie, to meet Elvis for an autograph turns the tide; she persuades her father to comply, much to Elvis's thrill.
When the day finally arrives, Elvis arrives at the White House alongside Jerry, though security confiscates his weapons. He comes bearing a unique gift for the President—a commemorative firearm, which will go through stringent checks before presenting. Next, he meets with [Dwight Chapin](Evan Peters), Nixon's special aide, who coaches him on the etiquette of the Oval Office. Elvis finds the entire situation amusing and prepares to share a poignant story about his stillborn twin brother and the complexities of his mother’s emotions.
Despite his excitement, Elvis inadvertently breaks a multitude of protocols during the meeting. However, he manages to impress Nixon, sharing heartfelt views on youth and family. Transitioning into politics, he expresses disdain for the Beatles, criticizing them for capitalizing in America while disparaging the country. The conversation eventually shifts to his desire for the federal badge. Nixon, seeing an opportunity, suggests that Elvis will receive his badge in exchange for an autograph and a photo with his daughter.
Elvis agrees, but only if he can include his friends, who have been kept outside. In a generous gesture, he presents the confiscated firearm as a gift to Nixon, who is quite taken by the King of Rock and Roll. By the end of the day, at 4:30 PM, Elvis is officially sworn in as a Federal Agent in his hotel room, marking an unforgettable day in history.
