Joe Gideon, a dynamic force of creative energy, navigates the demanding world of his latest Broadway musical, NY/LA, while simultaneously working on his film, The Stand-Up. A self-identified workaholic with a taste for excess, Joe's life is a whirlwind of chain-smoked cigarettes, a cocktail of medications, and moments spent preening in front of the mirror as he ritualistically declares, > "It's showtime, folks!" This mantra barely conceals the turmoil roiling beneath his meticulously curated surface. His ex-wife, Audrey Paris, serves as a continual reminder of his tumultuous past, often disapproving of his womanizing tendencies, while his live-in girlfriend, Katie Jagger, and young daughter, Michelle, offer him brief interludes of peace.
As tensions mount in Joe's life, his frustration with the editing process erupts into conflict during a rehearsal, resulting in an explosive display that leaves the show's financial backers bewildered and further deepens Joe's sense of alienation. In the midst of this chaos, Katie and Michelle provide a touching homage to the late Bob Fosse that softens Joe's hardened heart and leaves him momentarily moved to tears, offering a glimpse of hope amidst his creative disarray.
However, just when Joe starts to grapple with the chaos, his health spirals downward. During a table read for NY/LA, he suffers from intense chest pains, leading to a critical hospital visit where doctors diagnose him with angina. As his condition worsens, his reckless behavior escalates within the confines of the hospital, where he continues to smoke and drink, surrounded by a cavalcade of women despite his precarious health.
The mounting strain affects his relationships, particularly with Audrey and Katie, as the release of The Stand-Up is met with harsh critique, further amplifying Joe's emotional turmoil. Ultimately, Joe's relentless pursuit of creative excellence proves too much for his frail body to endure, culminating in a dire coronary incident that leaves him in critical condition.
As Joe hangs by a thread during coronary artery bypass surgery, those behind NY/LA hatch a plan to profit from his potential demise, betting on his life for a hefty insurance payout, revealing the cold business side of showbiz. Meanwhile, as his life support systems thrum ominously, Joe's mind wanders into a lush realm of musical reverie featuring characters from his past—his daughter, his wife, and his girlfriend—each performance a pointed reflection of his past misdeeds. The accumulating weight of their discontent starkly illustrates that he cannot escape his fate.
As medical professionals scramble to revive his fading life, Gideon capitalizes on a fleeting moment of clarity and makes a daring escape from his hospital bed. He traverses the twisting hallways of the hospital and the autopsy ward, embodying the five stages of grief that have been central to his stand-up routine: anger, denial, bargaining, depression, and ultimately, acceptance. With mortality looming over him, each imaginative sequence becomes increasingly extravagant, mirroring the inner chaos he grapples with.
In a climactic attempt to hold onto life, Joe's psyche manifests a grand variety show, a celebration that features a veritable roster of figures from his history. He takes center stage for a spectacular performance of "Bye Bye Life," a whimsical take on "Bye Bye Love" that captivates the audience with laughter and applause. As he teeters on the edge of existence, he finds solace in the understanding that he can express his gratitude to those who have impacted his life, a chance missed while confined to his hospital room. With one last burst of creativity, Joe's vision culminates in an opulent finale, journeying down a hallway to meet Angelique before the screen abruptly cuts to a somber scene of his lifeless body being zipped into a body bag.
