NCIS (season 8)

Following Jackson Gibbs' confrontation with Paloma Reynosa, he is put in NCIS protective custody at his son's house. A few months later, the death of a helicopter pilot leads the team back to the Reynosa Cartel's vendetta with Gibbs, leading team members to become targets. Paloma Reynosa, head of the cartel, plays a game of cat and mouse with NCIS as she makes a wide trail through the US, expanding her cartel's influence. Tensions erupt when Alejandro Rivera calls Abby on her bluff over the sending of the report on the Pedro Hernandez murder and threatens her in front of Gibbs. Knowing of his involvement in the Reynosa Cartel, NCIS lead Alejandro Rivera into a trap at a safehouse by tricking him into thinking his sister is dead and those responsible are in protective custody. Rivera takes the bait and intends to exact revenge, but ends up fatally shooting his own sister. Meanwhile, Leon Vance, whilst putting the report implicating Gibbs in a place no one will find it, receives a mysterious text message from Eli David, Director of Mossad claiming "I found him".

Final Appearance of: Alejandro Rivera and Paloma Reynosa

A teenage girl is kidnapped from her high school on the Quantico marine base, prompting NCIS to investigate. Nicholas Mason, the missing girl's grandfather, complicates matters when he arranges a ransom drop without informing NCIS. The team find a trail of dead bodies leading back to Mason, who admits he was a part of a black operations team that worked within the law, but outside the chain of command. Someone is using Mason's granddaughter to lure him out of retirement and lead them to the other team members. The kidnapper is the girl's high school English teacher, who was formerly a member of Mason's team and is seeking redemption for his past actions by killing off his team-mates. Meanwhile, three interns are assigned to NCIS; Abby is suspicious after her last assistant's attempt to kill her, Palmer feels ineffective after Ducky bonds with his intern, and McGee must contend with an intern who shows no interest in field work at all. Using an elaborate ploy, the team manages to trick the kidnapper into revealing where he was hiding the girl and arrest him. Meanwhile, the disobedient intern begins showing an interest in law enforcement and Gibbs hands him an NCIS application form.

NCIS responds to an emergency phone call after Heather Dempsey, a Marine bomb technician, shoots and kills an intruder in her home. Dempsey initially evades the investigation, but the team quickly find evidence she was not alone at the time. Her lover is revealed to be a senior FBI agent; the intruder a hit man. They learn that Dempsey's brother was shot and paralyzed by a man named Abbott in a gang war, and that the FBI lover recommended protective custody for him after he testified to escape jail time. Dempsey started a relationship with the agent to learn Abbott's new identity and location. When he learned that Dempsey was searching for him, Abbott hired the hitman to kill her before she could kill him. Because hiring the hitman was not part of his immunity deal, Abbott is arrested. Meanwhile, Tony is excited to be chosen as the face of NCIS' new recruitment campaign, but Director Vance decides Gibbs promotes the qualities NCIS is looking for more than Tony does.

The team is involved in an international incident as they investigate the murder of an American petty officer whose case is connected with a Royal Navy ship. Complications ensue when someone tries to get the ship to depart before NCIS can properly investigate. They discover that the murder was over a large amount of stolen CIA money, used to pay off warlords and dictators in Africa. At first, the team suspects that the Royal Navy liaison officer is responsible, but quickly find out that he is actually an MI6 agent who was framed for the theft. With his help, they track down the real culprit, the corrupt CIA handler who was in charge of the money.

The NCIS team investigate the death of a Navy researcher who was hit by a bus in the middle of a busy street. They are surprised to find that her entire body is covered in elaborate mathematical formulae, but begin to suspect her death was nothing more than an accident after finding evidence that she was becoming increasingly paranoid. Recognizing the researcher as a kindred spirit because they share similar thought processes, Abby starts to become fixated on solving her equations and her new-found obsession drives a wedge between her and the rest of the team. As the team discover that the researcher was being poisoned, Abby deduces that the formula is a method of converting bacteria into fuel. The trail leads back to a jealous co-worker, who poisoned the researcher in order to take her job. Meanwhile, Tony's latest fling causes trouble when she suggests role playing, but refuses to tell Tony what she has in mind. Her fantasy is later revealed to be Tony Manero from Saturday Night Fever, evidenced by a very uncomfortable Tony attempting to sneak out of the Navy yard in a white disco suit.

When investigating a murder, the team stumbles across a piece of an old nuclear bomb that had been lost during the Cold War. Because the victim had connections to Tony's father, they track him down and question him. Eventually, much to Tony's annoyance, Gibbs recruits DiNozzo Sr. to use his contacts to infiltrate a private party attended by arms dealers. They discover that the CEO of a salvage company stumbled across the nuclear bomb and plans to sell it on the black market. The CEO is arrested, and both DiNozzos finally reconcile their differences with one another.

The team is designated to protect Eli David (Mossad Director & Ziva's father) during a NCIS conference. They must deal with three Palestinian terrorists trying to kill him. The episode ends on a cliffhanger when, after an attack by the terrorists at the conference apparently fails, Vance and David go to a safe house. Gibbs cannot reach them on the radio and Officer Hadar is shown to be lying dead at the safe house.

Final Appearance of: Amit Hadar

Gibbs arrives at the scene to find Hadar dead, Vance critically injured, and Eli missing. Eventually, the team tracks down Eli, who had gone into hiding to elude his assassins. They then deduce that the man who planted the bomb is an insider at NCIS. At the hospital, the NCIS San Diego station chief, angry at Vance and Eli for inadvertently ruining his scheme to become director, reveals that he planted the bomb and attempts to murder Vance. However, Vance manages to subdue him. Before Eli returns to Israel, he reconciles his differences with Ziva.

The NCIS team investigates the disapperance of a Navy officer who is the sole witness in an upcoming murder trial. Annie Wersching guest stars as Deputy District Attorney Gail Wash.
