In 1967, a young Tony Soprano embarks on a journey with Dickie Moltisanti to celebrate the return of Dickie's father, "Hollywood Dick" Moltisanti, who arrives home with his new Italian bride, Giuseppina Moltisanti. This tight-knit group is part of the DiMeo crime family, which includes notable figures like Johnny Soprano, his brother Junior Soprano, and comrades such as Silvio Dante, Paulie Walnuts, and Buddha, who is Pussy Bonpensiero's father.
Amidst their lives, a significant event unfolds as a black taxi driver is brutally assaulted by white police officers, igniting riots in Newark. In this climate of unrest, Harold McBrayer, one of Dickie's associates, decides to join the chaos. Meanwhile, a carnival becomes the backdrop for turmoil as both Johnny and Junior get arrested, leaving Tony as a mere observer. The repercussions are severe as Johnny gets handed a four-year prison sentence.
The situation escalates further when Hollywood Dick exhibits his violent nature by kicking Giuseppina down a flight of stairs, prompting Dickie to confront him. In a cruel twist of fate, Dickie ends up killing his father and cleverly stages the scene to appear as if Hollywood Dick had perished in the riots by incinerating his body in his own drainage supply building.
As Dickie grapples with his choices, he pays a visit to his uncle, Sally, who is imprisoned for a family crime. Their meetings lead to Dickie seeing Giuseppina as more than just a wife, but as a sweet indulgence. Meanwhile, young Tony finds himself tossed out of school for initiating a gambling scheme.
Four years later, Johnny is finally welcomed back from prison, and at a heartwarming reunion, Dickie and his wife Joanne introduce their infant son, Christopher, whose wails trigger a comment about some babies having innate wisdom.
As tensions rise, Harold returns from North Carolina, determined to carve a niche for a black-led crime operation in Newark, while Giuseppina's affair with Harold complicates matters further. A bloody rivalry erupts between Harold's crew and the DiMeos, culminating in a shootout that takes Buddha's life.
Tony's academic struggles continue; he steals geometry exam answers, much to the concern of his school guidance counselor. The counselor informs Livia, Tony's mother, about his exceptional intelligence, and although Livia tries to bond with him, her mention of her mental health struggles only drives a wedge between them.
At a wake, Tony approaches Dickie, seeking Elavil for his mother, but Dickie appears reluctant. Tensions peak when Junior has an accident that brings laughter from Dickie, inciting Junior's fury. Dickie attempts to woo Giuseppina back, only to be heartbroken when she confesses her affair with Harold. Enraged, Dickie resorts to drowning her in the sea.
Seeking guidance, Dickie visits Sally, who advises him to keep his distance from Tony for the boy's well-being. Despite bureaucratic pressures, Silvio encourages Dickie to mend things with Tony. However, tragedy strikes when Dickie is shot in the head by an unknown assailant, with orders stemming from Junior Soprano.
The climax approaches as Tony, overwhelmed with grief, gazes at Dickie's lifeless body at the wake, forever haunted by the choices that led to this devastating end.
