Twenty-year-old Will Hunting (Damon) of South Boston is a self-taught, genius-level intellect with an eidetic memory, though he works simply as a janitor at the Massachusetts Institute of Technology, and spends his free time drinking with his friends, Chuckie (Affleck), Billy (Cole Hauser) and Morgan (Casey Affleck). When Professor Gerald Lambeau (Skarsgård) posts a difficult problem taken from algebraic graph theory as a challenge for his graduate students, Will solves the problem anonymously, stunning both the graduate students and Lambeau himself. As a challenge to the unknown genius, Lambeau posts an even more difficult problem and chances upon Will solving it. Fearing he will lose his sole means of (a meager) income, Will flees and skips going into work the next day. That night, Will meets Skylar (Driver), a British orphan about to graduate from Harvard, who plans on attending medical school at Stanford.
Mob boss Paul Vitti narrates a brief history of the Mafia: in the wake of Albert Anastasia's death, the dispute over who among Vito Genovese, Carlo Gambino and Joe Bananas will ascend to mob supremacy results in the Apalachin Meeting in upstate New York. The meeting is raided by the FBI, and the Mafia does not call a summit again until the present day.
Near the completion of his sentence in Sing Sing prison, Paul Vitti's life is threatened by assassins and corrupt guards while incarcerated. He fakes insanity and starts singing showtunes from West Side Story to get the attention of Ben Sobel, who previously hung up on him while attending his father's funeral. The FBI calls in Ben to see if Vitti is really insane. This appears to be the case, and the FBI approves Ben taking Vitti out of prison, into his own custody, for further therapy. On their way out in Sobel's car, Vitti reveals that he faked it. Needing some therapy himself after his father's death, a grieving Sobel talks Vitti into finding a regular job (as requested by the FBI). Vitti attempts to find a legitimate job (he tries a car dealer, a restaurant, and a jewelry store), but his rude manners and paranoia only complicate things further (which end up in him getting fired each time).

Sabina Spielrein arrives at the Burghölzli, the pre-eminent psychiatric hospital in Zurich, with a typical case of hysteria and begins a new course of treatment with the young Swiss doctor, Carl Jung. He is using word association and dream interpretation as part of his approach to Freud's radical new science of psychoanalysis, and finds that Sabina Spielrein's condition was triggered by the humiliation and sexual arousal she felt as a child due to her short-tempered father's habit of spanking her naked. These conflicting feelings were compounded by her instinctive knowledge (imparted by an angel's voice that speaks in German) that she had done nothing to deserve such a punishment and in fact that she may have been a stand-in for her mother in her father's abuse (since her mother was unfaithful). Also, her affluent Russian Jewish family afforded her an exceptional education in preparation for university study, although not on the subject of sex, and she was a virgin.
