Plot
In the Bronx in 1959, waiter and aspiring singer-songwriter Vincent "Vinnie" Vacarri is informed by his best friend and piano accompanist, Gino "G.G." Pilato, of their upcoming time slot at a recording studio, while working at his family's restaurant. After fighting with the mobster who owns the studio, he later tells his mother he lacks the necessary charisma to be a singer. Inspired by observing his friend Tomaso DeLorusso charismatically playing saxophone at a New Jersey nightclub, Vinnie convinces him that he is destined to be a headline act. Over the next few months, he molds him into a singer under the name "Tommy Dee" and produces a record with him. In order to promote Tommy by starting a record company, he reluctantly asks his father Frank for a $10,000 loan, criticizing him for selfishly abandoning his family for money and women.
Vinnie presses Tommy's records, and eventually Tommy successfully performs his debut single "Here Is My Love" on disc jockey Walt Bennett's show. Afterward, Walt pretends Tommy's song is mediocre until Vinnie bribes him into putting Tommy’s record in rotation. Later, Vinnie convinces Teen Scene magazine editor Brenda Roberts to feature Tommy on the magazine's upcoming cover. Sometime later, Tommy performs his follow-up single "Sweet Little Lover" on the television show National Bandstand, ignoring the rehearsed choreography and spontaneously interacting with the female audience. While celebrating his new success at the family restaurant, Vinnie becomes intoxicated, berates a clumsy waiter, and complains that Tommy will not follow his advice to study acting, frightening an overly concerned Brenda.
Sometime later, Vinnie gives his father a check to repay part of the loan, who warns him to remain humble and protect his investment while simultaneously advising him to draw up a contract with Tommy and recruit more clients. Later, Vinnie meets with Phil Delano, an agent from I.A.A., a large talent agency, and agrees to find Tommy a movie role. Meanwhile, following his father's advice, he transforms busboy Guido Bevaloqua into a singer named "Caesare" and assuages a jealous Tommy when he sees Vinnie grooming Caesare instead of joining him on tour. Later, Vinnie arranges a tryout for Caesare at a small club. In the dressing room, Tommy's advice to Caesare to smoke to calm his nerves sickens Caesare. On stage, he nervously runs off before finishing the first song. As Caesare vomits in the alley, Vinnie reassures him that he will not let him down. Afterwards, Vinnie creatively markets Caesare by splashing his photograph across town. As both continue rehearsals, an abandoned Tommy expresses a desire to obtain the part in a television series that Vinnie denied him and threatens to fire him. At Caesare's next concert, girls attack him on stage while he is performing his debut single "Baby", ripping his clothing, but once more security is added, he successfully finishes his performance.
Instead of allowing Caesare to tour, Vinnie places him in seclusion to increase his mystique. After five months, a restless Caesare borrows Gino's car to spend a romantic evening with Teen Scene reporter Ellen Fields. While he is returning, a cop gives him a ticket for running a red light. To prevent the misdemeanor from being publicized, Vinnie gives the officer concert tickets and threatens to drop Caesare as an act. When Vinnie hands Brenda a report, revealing that Ellen, her best reporter, has had similar relationships prior to her fling with Caesare, Brenda warns that Ellen's dismissal will upset Caesare. However, Vinnie claims that because he will be on tour, Teen Scene can cover the story exclusively. The tour begins in Memphis, Tennessee, but in the theater, Brenda criticizes Vinnie for being manipulative and reminds him she will cover his acts without special favors. After winning over the Memphis audience with his Elvis-inspired song "However Dark the Night", Caesare opts to switch management and signs with Phil Delano, with Gino following him.
Returning to his old neighborhood, Vinnie is unmotivated until his mother finally inspires him to return to the restaurant. Months later, he invites Brenda to witness him perform, but she declines. One night, Brenda encounters him on stage performing his own self-written composition "I Believe It Can Be Done", approvingly nodding at him.
