Vince Everett, portrayed by Elvis Presley, is a young, 19-year-old construction worker who seeks a respite from his demanding day by visiting a local bar for a drink. However, things take a turn when a drunk man recklessly splashes his drink onto Vince's face, leading to an unexpected brawl. In the heat of the moment, Vince inadvertently kills the man while defending himself.
This encounter leads to Vince's arrest and subsequent sentencing to serve a term of one to ten years for manslaughter. Inside the state penitentiary, he finds himself alongside a seasoned inmate named Hunk Houghton, played by Mickey Shaughnessy, a once-famous country music singer now serving time for armed robbery. Recognizing Vince's potential, Hunk begins to mentor him in guitar playing and encourages him to shine in an upcoming inmate talent show that's expected to be broadcast across the nation.
Due to his newfound fame, Vince attracts a flood of fan mail, though Hunk makes sure to keep it hidden from him. To the surprise of Vince, Hunk later persuades him to enter into a partnership for their music act. Yet, the path to success is fraught with challenges. After retaliating during an inmate riot, Vince faces harsh punishment, while Hunk's attempts to bribe the guards go unheeded.
After a period of 14 months, Vince is paroled for good behavior, and the warden presents him with the fan mail, revealing Hunk's intent to protect him from the pressures of fame. Hunk promises Vince a job as a singer at a nightclub, setting the stage for his return to the outside world.
Upon his release, Vince finds himself living in a modest flophouse, and soon heads to the nightclub, only to be disappointed by the club owner's refusal to hire him as a singer. Instead, he is offered a busboy position. While working, he encounters Judy Tyler, a young promoter named Peggy Van Alden, who encourages Vince to take the stage. During an impromptu performance, Vince’s anger peaks when he feels disrespected by an unruly customer, leading him to smash his guitar in frustration and leave the venue.
Peggy, however, believes in Vince's talent and persuades him to record a demo to help him assess his singing ability. With her assistance, he records "Don't Leave Me Now," which Peggy presents to Geneva Records. The initial response is lackluster, but when she informs him that the song has been sold, Vince's dreams take a hit. An awkward dinner party reveals tensions between Vince and Peggy, culminating in a heated kiss when she confronts him.
Weeks roll by, and dismay strikes when Vince discovers that Mickey Alba's version of his song has been released instead, with no credit given to him. Angry yet determined, Vince suggests forming their own label, Laurel Records, with the aid of attorney Vaughn Taylor. After recording "Treat Me Nice," they face universal rejection. However, with Peggy's networking, they secure airplay for the song from disc jockey Dean Jones, propelling it to success.
Later on, amidst rising fame, Vince invites Peggy for a celebratory dinner but is disheartened to learn of her date with Teddy. His increasing popularity lands him an invitation to perform on a television variety show in New York, a stage that proves pivotal in his career. Just when everything seems to fall into place, Hunk's appearance after his own release adds tension, revealing the rift between Vince's success and the sacrifices of his friend.
As success turns Vince into a self-centered celebrity, his relationship with Peggy becomes strained. Hunk’s persistent dissatisfaction culminates in a confrontation that leaves Vince physically vulnerable and potentially jeopardizing his career. In a moment of reflection, Vince arrives at the realization that he deeply loves Peggy, who reciprocates his feelings.
In the end, after a period of healing and reassessment, Vince sings "Young and Beautiful" for Peggy, finally feeling secure enough in his vocal ability and in his relationship with her. Their journey together progresses toward a hopeful future, marking the transformation of a once-troubled young man into a devoted artist and partner.
