In the vibrant backdrop of New York City, a group of seasoned comedians congregate at the famed Carnegie Deli, reminiscing about their glory days in the entertainment industry. Their conversations inevitably lead them to the unforgettable theatrical agent, Broadway Danny Rose, portrayed by Woody Allen. His eclectic roster of underappreciated talent includes a blind xylophone player, a one-legged tap dancer, a one-armed juggler, skillful balloon folders, and a remarkable blonde-haired virtuoso adept at playing water glasses.
As they trade anecdotes about Danny's unwavering dedication to his clients, one comic proudly claims to possess the ultimate Danny Rose story, revolving around Lou Canova, a down-and-out, overweight crooner of Italian descent, brilliantly brought to life by Nick Apollo Forte. Lou, whose once vigorous fame was fueled by a single hit song from the fifties, is now grappling with a drinking problem and an inflated sense of self-worth.
The narrative unfolds as Danny, ever loyal to Lou, attends his nightclub gig. However, trouble brews when Lou, bound by alimony from a previous marriage, purchases a solitary white rose for his mistress, Tina Vitale, played by Mia Farrow. Knowing both Lou’s wife, Teresa, and their young daughter, Danny urgently advises Lou against his infidelity.
With a wave of nostalgia sweeping through the entertainment scene, Danny seizes an opportunity when the legendary Milton Berle expresses interest in talent for his upcoming nostalgia-themed television special. Danny, ever the optimist, convinces Berle to see Lou’s performance at the Waldorf. As Lou embarks on a rigorous exercise regimen, Danny neglects his other clients to focus on Lou’s comeback, yet Lou insists that Tina's presence is crucial for his confidence. Reluctantly, Danny agrees to act as a decoy for her when he picks her up.
On the day of the show, Danny pushes beyond his usual Manhattan confines to fetch Tina, only to find her embroiled in a heated argument with Lou on the phone. Desperate to avoid a meltdown, Danny Christianize’s eager to reassure Lou and coax Tina into attending the performance, trailing her to her fortuneteller, Angelina. Inspired by Angelina's counsel, Tina decides to confront her past as she attends a party at a lavish estate where her ex-lover, Johnny Rispoli, played by Edwin Bordo, complicates matters further by stalking her and confronting Danny.
As events take a turn for the dangerous, the Rispoli brothers, in pursuit of retribution, capture both Danny and Tina and transport them to a secretive warehouse. With panic rising, Danny, under duress, deflects their attention toward a different target, Barney Dunn, a notoriously bad ventriloquist. In an adrenaline-fueled escape, Danny and Tina manage to flee the warehouse, leading to a series of wild and humorous misadventures.
Returning to the theater just in time, Danny finds a sober Lou preparing to perform, much to their audience's delight. After Lou's triumphant return to the stage, he confides in Danny about signing with another agent and rekindles his relationship with Tina. While at first their romance flourishes, Tina’s growing discomfort and complications from her past eventually catch up with them.
On Thanksgiving Day, an encounter between Danny and Tina leaves lingering feelings unspoken. Despite their intricate bond, they face a rift fueled by regret and unresolved emotions. Eventually, Danny chases after Tina, symbolically crossing the streets of New York to reclaim their connection. As the story concludes, the comedians at the Carnegie Deli chuckle over the legacy of Broadway Danny Rose, proclaiming, “They even named a sandwich after him–at this very deli.”
