The young Gene Krupa brings home a set of drums and places them in the family room as his mother and brothers look on, while his father makes his stance clear once again: he wants Gene to become “somebody fine...a priest, maybe.” On the brink of high school graduation, Gene resists the idea of seminary life and insists that his future lies behind a drum kit. When his father finally destroys the drum set, Gene vows to find a way to keep playing, believing he has a chance to earn money by jamming with a group.
During early rehearsals, Krupa meets a girl, Ethel Maguire, whose attraction to his drumming grows into something deeper. At a swim party they share a long, candid conversation about dreams and future plans. Ethel reveals she wants to move to New York City after graduation to study and write music, and the pair start to fall in love.
After his father dies, Krupa tries to honor his memory by pursuing the priesthood, but the seminary life unsettles him. He imagines “syncopated versions” of Ave Maria when prayer should calm him, and even after a year there, the drumbeat of his true calling continues to pull him away. The priest counseling him frames the priesthood as a fulfillment, not a penance, and suggests a summer back home to reconsider whether this life fits him.
Back at home, old friends keep the music alive in a local speakeasy, and Krupa’s curiosity about performing returns. He is invited to sit in, and his rhythm rekindles his appetite for music. Eventually he quits the seminary and joins the band, his mother quietly expressing disappointment while Ethel urges that their music might rise above the dives they’ve played in. The couple decides to move to New York, where opportunities feel more real even if the path remains tough.
In New York, the trio wrestles with finding steady work. Ethel lands a job as a switchboard operator, while Gene and his friend Eddie Sirota embark on recording sessions and gigs in elite clubs. At an upscale party, Krupa takes the spotlight with bandleader Tommy Dorsey, his brother Jimmy, and Red Nichols, who offers him a position in his pit band for George Gershwin’s new show Strike Up the Band.
Krupa’s star begins to rise as he records with top ensembles and plays in fashionable venues. A performance of “Cherokee” with the Benny Goodman Orchestra marks a significant breakthrough, and his career rapidly accelerates. The attention and success bring a volatile mix of exhilaration and excess: he hosts wild parties, indulges in alcohol, and cheats on Ethel, which strains their relationship and drives a wedge between him and Eddie. A seductive singer introduces marijuana into his life, and his use of the drug spirals into a broader confidence crisis. Despite his growing fame as a bandleader, Krupa’s timing falters on stage, a problem he later traces to the drug. A crucial turning point comes when he is busted on marijuana-related charges, convicted, and sentenced to 90 days in jail. The case appears to be a frame-up, possibly the work of a jealous coworker, yet the legal result is harsh and career-altering.
Upon release, Krupa faces a difficult reality: the public now views him as an addict, and offers to join major bands dry up. He performs in dives and strip joints, struggling to find a path back to the music he loves. Ethel locates him in one of these venues and informs him that Tommy Dorsey is forming a new band that could use a strong drummer. She also convinces him to master reading music, a skill he never learned, and he studies under a member of the New York Philharmonic to prepare for the comeback.
Tommy Dorsey’s people want to showcase Krupa with a “special return appearance,” a moment that could redefine his career. The performance starts strong, but hecklers threaten to derail him. In a gesture of solidarity, the Tommy Dorsey Band drummer, Shelly Manne, steps up to keep the beat when Krupa falters, allowing him to recover and finish with a two-man drum solo that earns a standing ovation. The moment reinforces Krupa’s resilience and presence, even as the crowd’s reaction hints at a complicated trajectory ahead.
As the film closes, Ethel tries to slip away, worried that Krupa might relapse into old habits. He catches up with her and asks where she’s headed, asking, “without me?” Their walk into the night suggests that, despite the trials, they remain connected. In real life, the two married from 1934 to 1942, remarried in 1946, and stayed together until Ethel’s death in 1955, a testament to a relationship that weathered the drummer’s turbulent ascent.
