Several crises threaten Tony and his crew; for starters, rival boss Johnny Sack (Vince Curatola) is in prison, and the always-tense relations between the New Jersey and New York families are strained through the unpredictable behavior of Sack´s surrogates. Then there are the inevitable power struggles that ensue when certain family members are eliminated, by natural and other causes. Features: Four audio commentaries with writer/creator David Chase, writers Terence Winter and Matthew Weiner, and cast members Edie Falco, Robert Iler, Michael Imperioli, Jamie-Lynn Sigler and Tony Sirico.
