Tommy has trouble adjusting to the mundane life at his new firehouse and takes out his frustrations on street vendors hawking Sept. 11 memorabilia. Later, he has a confrontation with Johnny. Meanwhile, Sean plays a crude joke on Laura that backfires on him.

Chief Perrolli agrees to let Tommy come back to the station on one condition: The crew must vote unanimously to trade Sully for Tommy. Elsewhere, things heat up between Franco and Laura; Theresa files a restraining order against Mike; and Tommy's dad remarries.
