In the fourth-season finale, the sighting of Jimmy's “ghost” is the talk of the firehouse; Colleen blames Tommy for her failed relationship, and Tommy figures out a way to fix his own. Meanwhile, Franco and Natalie come to an understanding, as do Lou, Mike and Latrina; Tommy and his father take in a ball game.

Catch and Release is a film about a woman mourning her fiancé's death, who finds a more than welcoming shoulder to cry on in his best friend.
