The gang brings Woody's old girl friend to Boston to visit him and Frasier, still not yet confident about returning to psychiatry, decides to pay his bar bill by working as a janitor.

Diane spends a dark and stormy night worrying that Andy Schroeder has escaped and is out to kill her.

Diane arranges for a stranger to come into Cheers as part of an experiment in paranoid behavior, but then she provides an even better example as she waits for the gang to get back at her.

Diane and Sam try to rebuild Frasier's shattered ego when he starts drinking too much.

Frasier has been out on a date with a fellow psychiatrist, Dr Lilith Sternin, but things didn't go too well.

Because of Woody's civic election win, Sam needs another bartender, a job he gives to Carla. To celebrate, Carla whips up a batch of one of her powerhouse drinks for the guys. The day after, everyone has a hangover. What's worse, Carla, who imbibed and got drunk herself, has a sneaking suspicion that she took someone home and slept with him, that person she believes being one of the Cheers regulars. She confides in Sam alone, and after he tells her it wasn't him, she panics and they both ponder who it could have been, with her worse nightmare having it be Cliff. When her bed-mate ultimately reveals himself, Carla and Sam have to decide how best to handle the information. Two other revelations come to light in the aftermath of the drunken spree. And Sam makes an admission of his own to Carla to make her feel better about her own further revelation.

After Woody, Kelly and her father Lloyd arrive at Cheers talking about classical music (they'd been to a symphony), Rebecca joins in the conversation and impresses Lloyd. He invites her to a society function. Rebecca thinks it is a date and is thrilled to bits - but is in for a shock when she arrives. Meanwhile Esther Clavin has been put in a retirement home by Cliff, but whilst Cliff feels guilty, the others think he has murdered his mother.

Don Sentry walks into the bar and into Rebecca's life. He's the repairman called in to fix the bar tap. Although Don is not Rebecca's usual type, Frasier talks her into taking a chance when she states that someone like a Don is what she should be going after. Quickly, she falls head over heals, but Sam thinks she's settling for second best. He wants Rebecca to be his fall-back if in a couple of years he has not found "Mrs. Malone". Rebecca shoots back that he is an aging Lothario way past his prime. Frasier suggests to Sam, who is hurt by Rebecca's comments, that perhaps there is some truth to Rebecca's assertion about him and that he would benefit by group therapy for sexual compulsives. Sam does go to the meeting, and after a rough start, he does admit that perhaps he is no longer happy with his life.

Whilst watching the National Cable Ace Awards, the gang sees ex-waitress Diane Chambers winning the award for best writing in a mini-series. This leads to Sam calling Diane to congratulate her, and to find out that she is married and has children. Sam tells her Diane that he too has a wife and kids, and invites Diane and her husband to visit them.

Sam strongly believes Diane is lying and becomes really shocked when she walks into Cheers the following day to meet Mrs Malone. Meanwhile Rebecca's boyfriend Don proposes to her and she accidently says no, ends up heartbroken and agrees to play Sam's wife to fool Diane.

Sam and Rebecca have dinner with Diane and her husband, Reed Manchester. During the dinner Don arrives and proposes to her again, and this time she manages to say yes! They leave the dinner, and Sam thinks he must look like a fool. Then Diane's husband turns out to be a fake when *his* husband Kevin appears!
