As he and Sheila plan a birthday party for his dad, Tommy discovers that, unbeknownst to anyone else on their crew, Franco is studying for an upcoming lieutenant's exam. With the ongoing pressure of their work and home lives taking its toll, the firefighters at 62 Truck have a hard time staying true to their pledge to stop smoking. And when Jerry discretely asks for some help to cover the increase in his wife's medical care, Lou reluctantly agrees, even though he's tapped out, too. Meanwhile, Sean tells Franco that he is secretly dating Tommy's sister, Maggie. While out with his crew at a hot Manhattan dance club, Tommy immediately becomes the target of an overly-talkative younger woman, as Mike is encouraged by some friends from his Academy class to apply for a transfer once his probation is over. While Franco is pursued by an older woman with sex on her mind, reeling under the crushing financial pressure of having been fleeced by an accomplished con artist, Lou drunkenly calls his ex-wife to ask for a family heirloom watch that he wants to sell. But when he goes to her house to steal it and is badly cut by some broken glass, Lou begins wondering if his life is even worth living anymore. Meanwhile, as Tommy learns that his daughter Colleen is now a Born Again Christian, and Jerry realizes how hard it will be to move his wife into a less expensive care facility, Sean worries about what Tommy would do if he ever found out that he is seeing Maggie. At the Chinese restaurant where the elder Gavin has insisted his party be held, Tommy tries his best to keep his temper in check, especially after Janet shows up. However, when Tommy inadvertently spots them discretely holding hands underneath the table, he realizes that Janet is seeing his brother Johnny. Enraged, Tommy loses his cool and unleashes a vicious assault, leaving Johnny bleeding and badly injured on the street outside.
