Bobby 'Bacala' Baccilieri Sr. comes out of retirement to deal with a young hothead named Mustang Sally--much to the chagrin of his son and Uncle Junior.

A somnolent visit with the ghosts of Christmas past lands Tony back on Melfi's couch. With the annual pork-store holiday party approaching, Bacala reluctantly agrees to don the Santa suit that Pussy used to wear. Tony and Furio have a holiday surprise in store for the Russian who roughed up Janice.

A disparaging remark about his wife sets Johnny Sack off on a vendetta. Meadow decides to do volunteer work at the South Bronx Law Center; Furio hosts a housewarming party for the gang; Silvio and Chris make an offer to an old-time hit man named Lou DiMaggio; and Tony and Carmela find themselves at odds over the family's bill-consolidation strategy.

While the gang begins to turn on itself, Tony finds himself at the threshold.
