What does fate hold in store for Tony in the sixth season of HBO's multi-award winning gangster drama. 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.
