When the men are nowhere to be found, Sheppard and Ballard team up to investigate the death of young girl, who's a teenage gang member. With the wedding one week away, Billie Lou asks for Munch's help with her neighbor's abusive boyfriend. After Munch approaches him strongly, the boyfriend retaliates by coming to the Waterfront and slamming Billie Lou's head on the bar. Munch claims he came on strong with the guy, because his ""testosterone riddled behavior"" was due to the celibacy Billie Lou imposed on him, to make their wedding night more special. Billie Lou wants to delay the wedding until the welt on her forehead goes away in about 3 weeks. After Sheppard and Ballard solve their case, Sheppard reminds Lewis that his problem with her is not going to keep her from doing her job.

Lines of Fire

Bayliss returns to duty to discover the bosses have renovated the squad room in an attempt to make everyone forget the tragedy of last May. Gharty and Ballard have also returned and Ballard debates about whether she should ask Falsone to the Lodge party. New detective, Rene Sheppard, tells her just to go for it. Seizing the opportunity, Lewis goes for it and asks Sheppard to the party; it seems that he and Barbara have separated and are on their way to divorce. Meanwhile, Falsone speculates if he should ask Sheppard to the party. The first case Bayliss catches, now partnered with Munch, involves the dismembered body of Angelo Faltislo, a friend of Gee's cousin, Mario Giardello. Stivers and Falsone's case is similar: Leo Grimaldi, another friend of Mario, is also found dead. When Gee goes to question cousin Mario, he finds Mario's body in the same condition as that of his friends. Gee's estranged son, Mike Giardello, an FBI agent in Arizona, returns for the funeral. Mike asks Falsone (w

La Famiglia

Bayliss has interest in Sheppard; later he seeks advice from Stivers, who tells him to get in line behind Lewis and Falsone. Lewis and Sheppard interview the remaining twin and his mother; she confirms his story and they try to point to the dead twin's girlfriend. Meanwhile the friend of the teenage victim in Ballard and Gharty's case confesses that his friend wasn't shot in Baltimore, but rather D.C.; he drove his friend back to Baltimore so their parent's wouldn't ""kill them"" for buying drugs in D.C. Gee hopes to get the case moved to D.C. Mike Giardello puts in for his FBI transfer, but the only openings they have in the area are for liaisons to local police departments. He interviews with Gaffney, who is so open to the idea, he can't wait to tell Gee. That's something Mike was going to wait f

Brotherly Love

MGee (Mike Giardello) and Ballard investigate a double shooting at the home of a prominent sports doctor and his wife, a dermatologist. The doctor (who was wounded) did not realize the deceased (thought to be a prowler) was his sister-in-law. Munch contends with the IRS; his Waterfront partners want him to make sure that his cousin, their accountant, has been paying their taxes. The Waterfront needs a loan to pay for some improvements. Gharty has taken the day off, to take care of personal matters, like his recent separation from Flora. Munch has his hearing with the IRS; he owes $30,000 in back taxes. Bayliss and Sheppard discuss his sexuality and the possibility of a date. Falsone takes MGee and Ballard to meet an old fight man who knew their doctor. Ballard becomes excited while watching Falsone spar in the ring. MGee and Ballard's investigation lead them right back to the doctor's house, where his wife may be guilty of conspiracy to commit homicide. Gharty stops by the Waterfront t

Just an Old Fashioned Love Song

A woman brings to the homicide unit her mystery-writer husband's videotaped declaration that his literary agent is responsible for his murder. Ballard and Gharty catch the case -- only there is no body or crime scene. Meanwhile, Munch and Bayliss investigate the death of an elderly woman that occurred during a break-in -- was it a homicide? Munch would rather leave for his weekend rendezvous with Billie Lou. Ballard and Gharty's investigation becomes a red-ball as they find evidence in the writer's office that a crime was committed. A break leads to the arrest of the literary agent and his accomplice, although Danvers can't guarantee a conviction. Falsone asks Ballard if she would like to go out Saturday night; just then the jury comes back. And a sharp-eyed juror insures that justice is done.

The Twenty Percent Solution

Ballard is annoyed when she finds out that the fact that she had a date with Falsone is around the squad room. Munch has a doctor's appointment and he's not talking about it. Dr. Griscom calls on the homicide unit when he sees a number of deaths that are related by a poison named phosphozine. The FBI steps in on the poisonings and they put MGee in charge of a task force; they consider it an act of domestic terrorism. One of the victims was a priest; two others were his parishioners. Gharty suspects the communion wine. Following this idea, wine bottles are collected from churches around the city. A needle hole is found through one of the corks. A citywide canvassing of all places where wine can be purchased is launched. Gee disagrees with the bureau's policy of keep information from the public. One possible suspect is captured; however, strange as he is, he's not the one. Through an internal leak, the media is alerted and warns the public, sparking chaos. MGee suspects the source of the

Red, Red Wine

Bounty hunters shoot, killing the wrong man, as they enter a building where their fugitive---a man named Joe Errico---has shot at them (and subsequently gotten away). Gharty has vague memories of a drinking binge from the night before. Falsone and Stivers catch the bounty-hunter case. Sheppard, during her days with the fugitive squad, had dealings with the head bounty hunter. Gaffney stops Gee and MGee on their way in, Baltimore magazine wants to do a father and son piece, using the wine case as a focal point. Gee is not interested, especially about the use of the wine case. Gharty struggles as he tries to reconstruct the events of the night before. Munch is bothered by Gharty's stories of Vietnam and each grows to dislike the other - perhaps some competitiveness over Billie Lou is beginning to brew here. Bounty hunter P.J. Johnson, who was identified as the triggerman, is charged and placed in one of the holding cells, near some of his previously captured quarry. Within an hour his ba

Lewis is transported to the hospital, as is the passenger of the car that MGee hit. Gharty is worked up about women and finances, because he and Flora and their lawyers are going to be working out the financial details of their divorce. Gee & MGee are not interested in cooperating with the bounty hunters; however, Knoll is the only one who can get any information on the whereabouts of Errico from Errico's mother. She has promised to page Knoll when her son calls. (Joe Errico has gone south to Miami.) Knoll offers to pay the expenses of having homicide detectives go to Miami and work with him, but Gee declines that generous offer and sends his detectives separately. In Miami, Bayliss and MGee work with Knoll to capture Errico. Knoll offers to split the huge bounty with the homicide detectives, which they of course refuse. MGee decides that the best use for the bounty might be for the man whose wife had died from the injuries she sustained in the car accident.

Wanted Dead or Alive (2)

Mike Kellerman's new vocation is private investigation, where the majority of the work involves catching cheating spouses. Falsone and Stivers catch a case where a newborn baby's body is found buried behind a motel. A young couple had checked into the room where the baby was delivered. The room was paid for using the girl's credit card. When they locate the girl (Debbie at home with her parents), she collapses and is brought to the hospital. The boy, Craig, is also located. Both say that the baby was stillborn; however, the autopsy reveals that the baby took a breath after it was born, so the death is ruled a homicide. Falsone notes that of the two, only the boy Craig seems to show any compassion for the baby. Kellerman meets Sheppard for a beer and tries to ask her about Falsone's baby case, later he asks around the squad room. Kellerman is hired to conduct his own investigation by the girl's defense team. Gee demands that Falsone and Stivers find convicting evidence before Kellerman

Kellerman, P.I. (1)

Debbie Straub signs the plea agreement, pointing to Craig as the killer of the baby. Falsone wants more time to work on the case. Danvers reminds Kellerman there was a time when the truth mattered more than his paycheck. Gharty goes off when Sheppard and MGee ask to many questions about Kellerman's leaving of the homicide unit. Kellerman appears to begin doing the right thing, but doesn't pass anything on to anyone who might be able to do anything with it. Craig believes that Debbie isn't going to let him down and he has no plans to testify on his own behalf. Ballard searches for a dinner date when Falsone leaves a message he won't be joining her. When she sees him in the Waterfront later, she lets him know how she feels about his method of communication. The case goes to trial, Debbie testifies that Craig killed the baby; with no evidence to the contrary, the jury finds Craig guilty.

Gharty tells Billie Lou that he'll attend her bass-playing concert. Munch & Lewis with help from the ME and MGee, identify the body and then begin to piece together what happened to her.

Since Lewis can't be found, she partners with Bayliss. Second shift detectives Bonaventura and Austin catch word of the day shift's case. It seems the victim in Sheppard's case was a witness they had interviewed the day before about an online murder hoax. The detectives are informed about another murder that is scheduled for midnight. It's a red ball. The detectives try to put the clues together, but come up with nothing and must wait until the netcast begins before they can trace the killer.

Homicide.com

Ballard and Bayliss are called to the scene of the mysterious death of a woman, whose body is found at the bottom of a forty-foot cliff. This victim was to be married the following morning. The two detectives work to determine whether the death was accidental or intentional (via murder or suicide). Meanwhile Sheppard and MGee begin investigating the death of a movie patron, whose body was discovered after the show ended and the theater cleared out. MGee mentions to Sheppard that his sister is about to have a baby, which means Gee is about to become a grandfather.

Truth Will Out

Lewis and Munch begin to investigate the death of a Buddhist monk beaten to death. Lewis isn't interested in working the case with Bayliss, whom he feels, may become too emotionally involved.

Ballard and Gharty's case involves a man who was shot down in the street; the three witnesses that saw the shooter all have different recollections of his appearance. As a result, their prime suspect cannot be charged. Gee asks for Bayliss's assistance in the Buddhist murder and to Lewis's dismay, Munch abdicates his position in the investigation to Bayliss. Lewis and Bayliss take different approaches to the investigation. Bayliss's approach leads him to the man who committed the crime, but cornering his suspect leads to a showdown with guns and Bayliss fires a fatal shot. Later Bayliss tries to reconcile the shooting with his own feelings about being a Buddhist and being a cop.
