Question: What is threatening Paul Vitti's ability to lead his criminal empire? Title: Analyze This Movie plot: 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. Vitti and his consigliere Dominic are discussing the upcoming meeting and the Mafia's present-day problems. However, just as Dominic warns Vitti to look out for Primo Sindone (an up-and-coming Mafia Don who wants to be capo di tutti capi), gunmen drive past and kill Dominic. Psychiatrist Ben Sobel is dealing with his own problems: his son from his first marriage listens to his sessions, his patients are not challenging enough, and his Miami wedding to Laura MacNamara is coming soon. Sobel unknowingly rear-ends a car belonging to Vitti and the trunk opens, revealing a man bound and gagged inside, which Sobel and his son do not notice because they are arguing. Jelly, one of Vitti's made men, takes the blame, but Sobel gives Jelly his business card in case he changes his mind about compensation. During a meeting with his crew, Vitti suffers a panic attack and tells Jelly that he needs to see a psychiatrist, but it has to be kept a secret and Jelly recommends Sobel. Vitti visits Sobel, claiming his friend needs therapy. Sobel impresses Vitti enough to want to see him whenever necessary. Sobel goes to Miami for his wedding. Vitti, Jelly and the crew follow. Vitti explains he has been having a hard time (after failing to maintain an erection during sex with his mistress) and Sobel suggests the source of the problem might be stress. The next day Vitti has another panic attack and requests to see Sobel. Vitti explains his tragic history with his father to Sobel, who thinks this might have something to do with Vitti's problems. The wedding is interrupted when an assassin is killed by one of Vitti's thugs. Sobel confronts Vitti and argues with him until he becomes angry....
