The attorney, Caroline Poop, who represented Elaine in her short lived suit against Fish and Cage regarding the constant gawking directed at a beautiful delivery woman, returns. This time she is representing the beautiful delivery women, Jennifer, who now serves Fish and Cage with her own lawsuit for same-sex sexual harassment. Meanwhile, Ally makes a bet with Renee that she can tell a dirty joke and get more laughs. The duel is set for the bar downstairs in her office building.

Three intelligent, successful and motivated adults approach Judge Whipper Cone about the possibility of getting legal representation in their quest to have the courts approve a legal, binding, three-way marriage. Fish assigns Ally and Cage to the case, knowing Ally's incurable romanticism and Cage's legal acumen is a potent combination with Whipper assigned to the case. Ally is opposed, claiming the three-way relationship is morally repugnant, but Georgia, feeling punkish around the holidays, points out that the clients' triangle isn't very different from the one in which Ally, Georgia, and Billy find themselves. Georgia accuses Billy of being more relaxed and open in their marriage ever since Ally re-entered the picture. Whipper, herself experiencing an annual bout of Holiday Blues, causes Fish to propose marriage, even though both know he really doesn't want to.

Ally and Renee are bridesmaids at a friend's wedding. They both bristle at the absurdity of the rituals performed, and swear to never do it. Richard asks Ally to flirt with a wealthy new client. To Ally's chagrin, Cage offers no protest on her behalf, admitting he's undergoing smile therapy which has renewed his appreciation for behavioral reinforcement. Ally and Georgia try a case about overturning a prison warden's decision to refuse marriage for a life-term inmate.

A wealthy client is brutally murdered and the wife is implicated. Her only defense when caught red-handed is that she has no recollection of what had taken place. Billy, anxious to take on bigger cases, is the lone voice advocating for the firm taking the criminal case, but Fish and Cage ultimately decide it should be farmed out. Georgia, meanwhile, takes on a case about a heterosexual waiter suing for discrimination and wrongful dismissal when he's fired from his job for not being gay.

The crossover continues on The Practice S02E26 Axe Murderer (II).

Nelle is already making her presence felt in the change of office atmosphere when Fish dumps another groundless case on Georgia. Ling Woo, the unpleasant plant manager, is back to sue a nurse in her sister's plastic surgeon's office for misrepresentation of results from breast implant surgery. Georgia would love to drop the case but can't. She confronts Nelle for dumping it on her anyway, but Nelle justifies the reassignment by saying she and Ling are friends and would end up hating each other as a result of the lawsuit. Cage reflects on Ally's progress with a mediation case between Fish's minister and a jilted choir singer. Nelle moves on to Cage and confronts him about his resistance to the notion of a potential interoffice romance.

Cage continues to ride the high of his birthday gift from Nelle. It was a life changing night and has had a profound effect on his view of himself and his self-esteem in regards to women. The firm is defending another law firm, Johnson Biblico, in a suit alleging sex discrimination. Elaine is distraught that she won't be able to compete in the swing dance competition since her partner pulled his Achilles heel. Her hopes are raised when Ling reveals that she can dance swing and offers to enter with Elaine. Billy and Georgia continue to work on their relationship as part of the aftermath of Billy's almost-affair with Ally. They have started to see a marriage counselor, Dr. Hooper, who thinks it would be a good idea if Ally were to make an appearance.

Elaine finds a real, live six-week-old baby in a nativity scene manger and wants to keep him. Cage and Ally represent Elaine in her fight to gain custody, while the rest of the office (full of child-less lawyers) become enchanted with the baby. Even Ling considers having children. Billy attempts to reconcile with Georgia. In preparation for the Christmas party, Elaine convinces Ally to sing a sexy song but Richard and Billy have their reservations.

Ally is pursued by a barista, but she is turned off by his forwardness so she dumps coffee on him. Later she meets him in court, where he is presiding as a judge, and after a heated exchange of words Ally finds herself in jail. After the two of them work things out, they end up on a date. Meanwhile, John is upset by Nelle's snobbish elitist attitude towards the "small" people and Billy finally kisses his assistant Sandy.
