To make the next hockey game with the NYPD a wild affair, Tommy mends fences with his ex-co-captain, Ryan, who offers to enlist a fireman who is on leave for beating up three cops. As Lou's affair with Sondra heats up, and Mike comes to grips with Theresa's eating disorder, Franco counsels Sean on how to dump Carol, a woman he says is a bad kisser. And after another day at the track with Uncle Teddy and Arlo leaves him with plenty of cash for Janet and Sheila, Tommy is startled when Laura questions his motives and his sanity. Then, after she's the only one who can stop an angry man from attacking the firefighters removing his morbidly obese mother's corpse from her apartment, Laura gains some credibility with the crew. Tommy's plans for the hockey game play out perfectly when the police team loses their cool. Then, once the firefighters' win is assured, they unleash a cascade of violence that sends both teams tumbling into the street. When claiming to be gay can't help Sean get rid of Carol, Lou gladly agrees when his wife's boyfriend tells him that Phyllis wants a divorce. And after a bad day at the track forces Arlo to admit that his luck has run out, he stuns Teddy by claiming that he's in love with him. Meanwhile, during a visit to the firehouse, Father Mickey Gavin confirms that his cousin is having an affair with Sheila. So, when confronted by his colleagues, who give him vicious beating for the indiscretion, Tommy blurts out that Sheila is pregnant. After learning that Mickey revealed his secret, a call sends the crew to a fire where, as he is searching the building with Laura, Tommy becomes disoriented by his ghostly visions. But when Laura calls for help, Franco arrives and is injured when the ceiling collapses. As the tragedy causes both Jerry and Perroli to warn him to clean up his act, Tommy asks for a transfer and, after punishing Mickey, heads home to find that Janet has moved after learning about Sheila. Finally, as Franco's accident leaves Mike turning to Theresa for comfort, Jerry learns that wife, Jeannine, has Alzheimer's.
