With Damian confined to a chair and a new baby on the way, Sheila and Janet join forces and shake-up Tommy's family life.

The guys go stir crazy waiting for a job; Lou fakes his physical; a news team memorializes Jimmy; Tommy is saved by an unfamiliar face.

Tommy puts an end to Kelly's dull date and to his spell of uselessness; Lou becomes godfather; Colleen finds a dress; Tommy sits down for his interview.

What starts as a controlled interview takes a turn for the worse, ending in a full-on brawl. The beef continues even after the guys survive a harrowing scenario at a call.

The fallout from Tommy's 9/11 interview hits like a ton of bricks, and reporter Pam Keppler begins probing Tommy's personal life as well, which promises to bode ill for everyone in 62 Truck. So Needles proposes "to fight fire with fire," but Franco won't go along. Meanwhile, Sean works up the nerve to confront Emily over "the smell," and Tommy lays down the law to his family (Sheila included).

Tommy crosses an emotional line with Sheila and lures Lou into a psychological trap after he visits Ground Zero with the guys. Meanwhile, Franco challenges Lou's authority at the firehouse; and Sheila makes Colleen an offer (and won't let her refuse it).

Lou delivers Tommy's letters to Sheila and Janet behind Tommy's back. And "Francostein" runs a tight firehouse as Lou's interim replacement. Then he gets an opportunity to test his leadership skills on a call.

Colleen's wedding becomes an emotional affair; the guys tackle the mother of all fires.

Series finale: The guys at 62 Truck struggle to pick up the pieces and move on following a major fire. At the Fire Academy, meanwhile, a new batch of probies hear a familiar speech from a new leader.
