The film traces the rise and fall of Chicago mob boss Capone, portrayed by Ben Gazzara, whose iron grip over the Prohibition-era city shapes an underworld that thrives on fear, loyalty, and calculated violence. From a young streetwise opportunist to the most feared enforcer in town, Capone’s arc unfolds alongside a roiling cast of gangsters, politicians, and lawmen, all entangled in a deadly game of power.
In the opening sequence, a young Capone earns his scars and his reputation after a dramatic confrontation in a Brooklyn alley, a moment that foreshadows the ruthlessness he will bring to his criminal ascent. The encounter sets the stage for an alliance with the city’s looming powers and introduces the men who will become pivotal to his story, including Harry Guardino as Johnny Torrio, whose cool command and strategic mind guide Capone toward bigger schemes. Capone’s early years are marked by a quick pivot from a small-time hoodlum to a trusted enforcer who earns the respect of seasoned racketeers, one of whom is John Orchard as the calculating Dion O’Banion, a rival whose turf wars will ignite a ruthless battle for dominance.
The narrative accelerates as Prohibition reshapes the city’s criminal landscape. Torrio and his allies, including a dancer and barmaid named Iris Crawford, played by Susan Blakely, recognize the opportunity to bootleg and profit on a scale never seen before. The pair recruit Capone to Chicago to enforce their new order, and the decision to remove Jim Colosimo—known as Big Jim and portrayed by Frank Campanella—becomes a turning point. In a chilling act of violence, the young Capone quietly executes the boss in the back of a restaurant, an event that marks the brutal birth of the Chicago Outfit.
As the Outfit establishes its foothold, the film follows the deadly turf wars that define the era. A pivotal shootout in Joliet demonstrates Capone’s instinct for territory: the North Side under O’Banion, the South Side under Spike O’Donnell, and the Little Italy domain claimed by the Genna brothers, with Capone and his crew consolidating power in the Loop. This period features key figures such as Martin Kove as Pete Gusenberg and Robert Phillips as Bugs Moran, whose feuds escalate with brutal precision. The coalition and conflict among gangsters are mirrored by the ambitious, corrupt officials who attempt to manage the chaos, including George Chandler as District Attorney Robert E. Crowe and Royal Dano as Anton J. Cermak, the mayor who becomes a political foil to Capone’s influence.
The plot intensifies with a series of retaliatory strikes and strategic killings. Capone’s circle tightens as alliances shift after the murder of O’Banion and the subsequent hits on rival families. The iron will of Capone is shown in moments of calculated compromise, as when the Outfit’s reach is temporarily tempered by political pressure. Yet Capone remains impervious to the law, boasting of his untouchable position as long as corruption shields him. The film doesn’t shy away from Iris Crawford’s fate, a personal blow that deepens Capone’s resolve and his capacity for vengeance, a sentiment that drives his relationship with his most trusted enforcer, Frank Nitti, played by Sylvester Stallone. Nitti’s loyalty and ambition become instrumental as Capone navigates a city ready to turn on him when convenient.
The narrative crescendos as the city’s elected leadership seeks to rein in Capone’s violence. The new tone is set by John Finnegan as a NY Police Lt. in some scenes, and by the public pressure that culminates in a dramatic showdown with the city’s power brokers, including George Chandler again as Crowe, who threatens to indict Capone for the murder of government-leaning targets. In this tense climate, Capone’s men execute a sweeping, brutal assault on Moran’s organization—an act that lays bare the extent to which Capone will go to consolidate power, even as the city’s political class grows bolder in turning against him.
The legal portion of Capone’s saga unfolds with his high-profile tax evasion trial. The relentless pursuit by federal authorities culminates in a lengthy legal process that ultimately results in Capone’s conviction, not for murder or bootlegging, but for multiple counts of tax evasion. The judge’s sentence sends him to Alcatraz for eleven years, a punishment that signals the end of an era for the Chicago Outfit’s hegemony and a shift in the city’s criminal balance of power.
Health and time take their toll. By the late 1930s, Capone’s strength has waned, and doctors diagnose advanced syphilis, a disease that erodes his mind and memory. The film portrays the fragility of a once-formidable figure as his body betrays him, triggering riots and a further erosion of the control he once wielded with brutal efficiency. Capone’s decline continues in Florida, where his trusted ally Nitti—still by his side in these final chapters—wields a candid, almost merciless appraisal of Capone’s flaws: the man who ruled through fear is now a faded echo of his former self, haunted by memories of his past decisiveness and the empire it built.
In the end, Capone dies several years after his release from isolation, a life spent in bedlam and isolation, a stark contrast to the power he once commanded. The closing chapter focuses on the complex relationship between Capone and Nitti, with Nitti’s guarded assessment of Capone’s legacy underscoring the cost of leadership in the criminal underworld: ambition, loyalty, and a willingness to kill for power often leave a bitter wake. The film closes on a quiet, reflective note about how a man once at the center of a violent empire can fade into memory, leaving behind a city forever altered by his presence and the violence that defined an era.
The story is a careful, unflinching look at how one man’s appetite for control can reshape a city, drawing in real historical figures and the fictionalized human drama that surrounds them. It remains a portrait of charisma and brutality, of political protection and personal loss, and of the slow, inexorable march from the heights of power to a solitary, unmoored end.
