NCIS (season 2)

When an eight-year old blind girl (played by Abigail Breslin) and her mother are kidnapped to blackmail a Navy captain (David Keith) into transferring $2 million in government funds, Gibbs and his team are faced with a unique challenge. An unexpected twist is uncovered when Abby and McGee manage to trace the money. After helping them solve the case, Tim McGee who was on a brief transfer from Norfolk gets an unexpected surprise from Gibbs: he is promoted to a full-time field agent and as a result is transferred to the Navy Yard, becoming a permanent member of Gibbs's team in the process.

The mummified remains of a woman are found in an abandoned Marine home. The team discovers that the woman who had been missing for several months was wearing a wedding dress when she died, and may have been a victim of a serial killer, one who Kate profiles was abused as a child and will now go to the limit to make sure he finds the ideal wife for himself as he's attempting to create the perfect relationship. During the search for the murderer, McGee uncovers a similar case regarding a missing Petty Officer in Florida, and the team head to Florida to investigate. Upon arrival, they begin looking for connections between the women and the locations. Some clever forensics work from Abby, combined with profiling from Todd and Gibbs, reveals an unlikely suspect.

While on leave, two sailors discover the body of a young woman dressed in a Navy uniform but she's not actually a member of the Navy- she is in fact a civilian. Upon arrival, Ducky quickly links the murder to an unsolved case he worked on with another NCIS agent 10 years ago, and soon begins behaving strangely, acting very secretive and distant. When Gibbs corners him, asking for answers, Ducky reveals that the old case is the only one he has ever dealt with in which he did not identify the victim and as a result, it has become very personal to him. Realizing that Ducky has carried this case with him for ten years, Gibbs resolves to help him solve it for good and the rest of the team join in to aid their colleague. When a note is found at the new crime scene, the handwriting is matched to a similar one left at the other crime scene with McGee's dedicated detective work, combined with Abby's forensics, putting forward a suspect.

The NCIS team attends a crime scene, and end up finding multiple remains. When one set of remains is revealed to be an undercover FBI agent, the team realises that they have stumbled upon a dumping ground which the mob have been using for eighteen years to dispose of their victims. The FBI suspect an agency mole is responsible for the exposure and subsequent death of the murdered agent, and it appears as though Fornell is being set up to take the blame for what's going on. Gibbs then sets out to find the real mole and clear Fornell's name, using tactics that shock his team.

When an Iraq veteran is threatened and very nearly killed by a group of terrorists, the NCIS team steps in to protect her and her family. While trying to convince an FBI agent to help them, the team is convinced that they've discovered the bomber. However, things might not be what they seem when another car bomb nearly kills Tony and Todd during their protection duty of the Lieutenant Commander. A family secret may pose more of a threat than even terrorists could.

A Navy Commander dies after a successful surgery. At first glance, it appears that the sudden death might have been a case of spontaneous human combustion. While researching the dead man's past, the team discovers that he had gained a lot of enemies recently, not least of all a young ensign, who makes himself the prime suspect with some bizarre behaviour. However, while analysing the evidence from the scene of the death, Abby and Tony discover the truth, and in turn find a new suspect. In the meantime, Ducky develops a soft spot for the doctor who was treating the commander.

A Marine's wife shoots an intruder in self defense when he is about to rape her. At first the teams believes that man got what he deserved, but the theory changes when it is revealed that the wife had been leading a double life (while her husband was serving overseas). Upon speaking to the intruder's sister, the team further theorise that the whole incident may have been set up as a 'date' by the wife, who got cold feet at the last minute. However, when Abby matches the intruder's DNA to a sample already held on file, the entire investigation changes.

A Navy officer's body is found in a car pulled from a lake by a celebrity private investigator. The man had been missing for two years. The PI now wants to claim the reward posted by the family, but the NCIS team must complete the investigation to find the killer before the money is awarded. The case changes from accidental death to suspected murder when McGee discovers a bullet lodged in the car. The team initially suspect that the dead man's brother may be a prime suspect, but forensic evidence suggests someone unexpected is responsible for the killing.

After several months, Ducky and Jimmy finally start identifying the bodies in the meat puzzle they have been working on. It is not long before Ducky realises he testified in the court case of a would-be Medical Examiner named Vincent Hanlon who was accused of murder and was eventually jailed for eight years as a result. They soon discover that the dead men were involved in the case and it dawns on Gibbs that Ducky might be the next target. Tony and Kate are assigned to protection detail which means safeguarding Ducky and his elderly mother, but a mistake by Kate leads to Ducky being kidnapped from his home during the night. The team must race against time to find him before he ends up dead like all the other previous victims while Jimmy and Abby begin working together to uncover the truth.

A beautiful young MIT graduate (Danica McKellar) witnesses a sailor being strangled. Local police doubt her story, but McGee asserts that her account warrants further investigation. When a sailor's body is found at another location, the story gains ground. The witness also captivates McGee who, after a sudden twist in the investigation, ends up unknowingly holding the key to solving the case.

A Marine falls off a cliff, and his camera records him falling. The prime suspects are his wife and his best friend with whom he was staying in the camp. Gibbs finds out they had an affair behind a dead man's back and he tries to persuade them to blame each other. In the meantime, Abby reconstructs the damaged film footage on the camera and reveals a previously dismissed suspect to have been in the vicinity at the time of the death.

A dance club bartender wakes up in bed with a dead female petty officer and claims this was not the woman he came home with, despite the fact that he was drunk at the time. DNA tests reveal that he was telling the truth, but the team must still work to figure out whether this means that he didn't kill the dead woman. The victim's sister and a local corrupt businessman may know more than they are telling. Guest Starring Mýa.

When a Petty Officer working in Intelligence receives a pair of cobalt blue eyeballs in the mail, the NCIS team starts investigating the case. The sailor commits suicide during the investigation and after Abby matches the eyes to a South American girl in a photo with the dead man's lecturer, Kate and Tony must travel to the Triple Frontier destination of Paraguay to discover the truth.

A Virginia Beach bikini contestant drowns in a public bathroom toilet. When the team discover she posed partially naked in a magazine, and was pregnant at the time of her death, clues are revealed that lead to an unlikely suspect. Tony finds a juicy secret from Kate's past.

The team investigates a suicide case, believing that the main reason of her death is a nervous breakdown, but Ducky believes that she was actually murdered. FBI Special Agent Fornell helps them in the investigation. The team discovers that the dead woman was involved in a love triangle and that this may have contributed to her death.

A marine is found murdered on the school campus, and the team immediately finds a suspect. However, they are forced to start again when they find the suspect murdered. McGee and Abby discover a trace in the e-mails, called "Red Cell," which leads them to believe that the marine must have been involved in a serious death game.

Recurring characters: Brian Dietzen as Jimmy Palmer, Troian Bellisario as Sarah McGee.

The executor of a petty officer's will discovers the skeletal remains of a missing girl in the dead man's rented storage unit. As the petty officer is up for a Silver Star, it is very important that NCIS determines if he was a murderer within 24 hours. Soil samples and further forensics lead Abby to discover that if the Marine was the killer, he could not have acted alone. Tony and McGee find CCTV footage that suggests the Marine was entirely innocent. Tony also has to deal with his car being stolen.

All hell breaks loose at the NCIS office when Tony opens a mysterious letter containing a small puff of white powder which may be a deadly bacteria. Kate calls for help and as a precaution, she and Tony are put into a bio-hazard isolation room while McGee and Gibbs are left to discover who sent the envelope and their reasons for doing so while searching for a cure to help their friends before it's too late.

While the team investigate a double murder where the victims were shot in their car, Kate kicks Tony onto the ground and he notices a bomb on the car, saving Todd and McGee. Tobias Fornell of the FBI arrives at NCIS and notifies the team that Ari Haswari has returned to the US and may be on a personal vendetta to assassinate Gibbs. While McGee starts attempting to disarm the drone, Gibbs, DiNozzo and Todd take the warehouse and begin searching for Haswari. However it's not an easy approach as they're forced to storm the warehouse and engage in a vicious and bloody gunfight with members of Ari's terrorist group. All seems to be going well until Todd takes a bullet in the chest for Gibbs. It is soon shown that she's wearing a bullet proof vest but just when it seems to be all over, Kate is brutally murdered, having been shot in the head by none other than Ari himself who's been waiting on an opposite roof waiting to strike. The episode ends with Gibbs looking around for the shooter and then whispering a single name: 'Ari'.
