Law & Order season 15

Detective Joe Fontana (Dennis Farina) transfers to the 27th precinct, a stylish veteran uneasily paired with Detective Green when Lindsey Starr a former female Guardsman from the second Gulf War is found murdered—and evidence points to the vengeful Iraqi sister of an ex-inmate at infamous Abu Ghraib prison.

Special guest appearance made by New York City mayor, Michael Bloomberg.

• First appearance of Dennis Farina as Senior Detective Joe Fontana.

When a woman Donna Mclean is found dead after a ferry collides with a Manhattan dock, Detectives Fontana and Green become suspicious when they learn that the victim sustained a blow to the head and was seen in the water just before the accident, and the likely suspect is the ex-wife of a firefighter who left her to marry a rich "9/11" widow. But EADA McCoy soon learns that the defendant's crafty lawyer intends to position her as a victim of post-traumatic stress syndrome owing to 9/11, meaning that McCoy has to overcome extreme emotions common to every New Yorker.

When a prison gang puts out a contract on a Sing Sing corrections officer and his family, assigning the job to a newly released ex-con, the terrified officer pleads preemptive self-defense after he's brought to trial for the parolee's murder. As the trial proceeds, the gang attempts to affect the outcome of the case by sending a death threat to the presiding judge, who refuses to be intimidated. Shortly after the conclusion of the trial, McCoy discovers that the defendant's fears about the power and the reach of the gang were well-placed.

When two college students take flying leaps to their deaths, Detectives Fontana and Green discover that both students were participants in a secret testing program on a new anti-depressant run by a large drug manufacturer that has yielded a high rate of suicides, and more attempted suicides. EADA McCoy decides to vigorously pursue the CEO of the pharmaceutical firm for second-degree murder but his case hinges on convincing the judge to admit guarded clinical trial info.

The NYPD gears up to find the cop-killers who murdered two officers Calvin May and Dexter Richmond during an illegal firearms buy-and-bust sting, putting Detectives Fontana and Green on the trail of two suspects as Green risks his life to pose as a gun buyer, to gather evidence on the gun dealers. They soon discover the killers were tipped off to the victims' identities by a website displaying photos of undercover cops. Turns out the website is financed by a vengeful defense attorney (Isiah Whitlock, Jr.) whose criminal stepson was killed by the police; and now claims that he is protected by the First Amendment as McCoy and Southerlyn prepare to prosecute. McCoy is able to connect the hit men to the attorney who paid them to avenge the death of his gun-running stepson at the hands of the same detectives during a similar buy-and-bust several years earlier.

After a bestselling pulp-fiction novelist Nora Hackett is found dead in her hotel bathroom, Detectives Fontana and Green investigate and discover that the deceased recently had a liposuction operation performed by a careless plastic surgeon (Bruce Altman). EADA McCoy decides whether or not the case should be pursued in civil, not criminal court. But when District Attorney Branch sees a recurring thread of negligence in the doctor's past, McCoy files charges and bases much of his argument on the fact that the obsessed victim's many beauty procedures required psychological counseling that her greedy surgeon never suggested.

In a controversial episode torn from recent headlines, Detectives Fontana and Green follow the sensational murder of the wife of Connecticut Governor Riordan (Robin Thomas), but their spadework turns up a corrupt developer (as Kaplan, Željko Ivanek) whose business and romantic links to Riordan cause the official to step down in shame. However, EADA McCoy is stymied when he cannot get a third man (Jeremy Webb) to testify against the crooked business exec after he claims to have already married him, forcing the dogged McCoy to take the crucial gay marriage issue before the state's supreme court and Kaplan's defense attorney (Chris Sarandon).

A street thug-turned-radio personality (Jose Zuniga) who had a penchant for attracting headlines through "publicity stunt muggings" is thought to be faking again when he's shot and almost killed. However, when other bodies start to stack up, Detectives Fontana and Green now must believe the danger is for real, they begin to believe his story after they discover that the married jock was involved with a mobster's mistress.

After four people, including tourists, are shot dead on the same sidewalk, Detectives Fontana and Green learn that one was Roman Rybakov a philandering jeweler with criminal ties to the Russian mob who was cooperating with federal authorities, until someone close to the victim "ratted him out." In the meantime, the investigators find the hitmen, but EADA McCoy must wrestle with the federal prosecutor over jurisdiction; and both cases might hinge on the fact that the jeweler was an Orthodox Jew.

In the bloody wake of a massacre of heroin dealers, Detectives Fontana and Green track through a list of international criminals until they target their primary suspect, a drug-dealing Afghan warlord (as Khaleel, Christopher Maher) who's aided U.S. forces in Afghanistan and claims diplomatic immunity. But EADA McCoy and ADA Southerlyn fearlessly prosecute despite State Department pressure and a defense lawyer who claims his Afghan client was forced to push drugs in order to maintain his cover, and ultimately continue to aid American military efforts.

When a convicted child murderer (portrayed by David Groh) is released from prison, he is struck by a car and left for dead by a motorist. Detectives Fontana and Green are not enthused about finding out who ran him over.

Not long after Greg Emerson a wealthy venture capitalist is found slain in his spacious home, Detectives Fontana and Green suspect the victim's feckless young wife (as Marley, Andrea Roth), as well as the handsome contractor (as Tremont, Daniel Sunjata) who installed the security system and was romantically dallying with the wannabe widow. On the legal side, DAs McCoy and Southerlyn seek to turn the cheating wife against her ex-beau, but the bad boy's many "alibi girlfriends" and a second unexpected crime severely hamstring their prosecution.

Detectives Fontana and Green move to the beat of hip-hop when a legendary rapper is shot to death and evidence points to the victim's young protege (as Shawn, Sean Nelson) who was known to be cutting his own music on bootlegged street CDs, and more clues are found in one song's lyrics that describe a similar killing. As police tie in another previous murder, DAs McCoy and Southerlyn seek the email addresses from a thuggish record label's website that could unlock the case, even as the two prosecutors clash over admissible facts. As the investigation unfolds, Southerlyn's opinions put her sharply at odds with both McCoy and Branch, the latter of whom begins to feel that Southerlyn is not cut out to work in the DA's office.

When a loner Ira Walderman is found strangled to death in his rent-controlled apartment, Detectives Fontana and Green focus on both the victim's gambling habit and the building's owner who wants to convert it into a co-op, but the cops hit paydirt when they discover the dead man's nasty running feud with a spoiled pro basketball player.

After a wild car chase through Manhattan's streets leaves one man dead and a teen injured, Detectives Fontana and Green connect some dots and discover that the chase began in upstate New York after a hunting party was massacred by the now deceased driver, but finding the man who chased the murderer puts prosecutors in a bind. As the reluctant hero (as Stoller, Mike Pniewski) is publicly lauded for his efforts, prosecutors McCoy and Borgia carefully make their case that his poor decisions only endangered other lives.

When a TV network executive Lisa Taylor is found murdered, Detectives Fontana and Green suspect twins who were stealing from the organization until they discover a celebrity chef with whom the married victim shared an affair.
