The team discovered the truth about an inside job on the latest installment of "NCIS."

In "Page Not Found," Delilah (Margo Harshman) wants to dig into the murder of a naval intelligence officer overseas, so she goes to Gibbs (Mark Harmon) for help.

Lieutenant Jones (Colin Hanks) had been trying to take down the men behind the murder, who are also behind a nefarious website for the trafficking of illegal goods. The team suspects that Jones faked his own death and is now running the site.

Tony (Michael Weatherly) and McGee (Sean Murray) visit the former webmaster of the site, but they can't get information from her.

Later, CIA Case Officer Jim Brisco explains that they pulled Jones out and faked his own death for a deep cover to help with a money laundering operation. The team then finds a tissue in Jones' apartment, which they investigate to find that it contains signs of malnutrition and sedation, meaning he's a prisoner. They soon discover that Brisco is the one who was holding him prisoner and torturing him for codes so he could sell the intel.

They find that Brisco's daughter was working with him to get money to pay for med school. She makes a deal, and in the end, Jones reunites with his fiancee in time for his wedding.

Meanwhile, both McGee and Delilah talk to Tony for advice about their relationship.

Yet, Delilah reveals that she is going to take an analyst position in Dubai, meaning they will enter into a long-distance relationship.

On the next episode, "Alleged," "A Navy officer is found dead on a rural road. The investigation focuses on whether the victim was murdered as a result of a bar fight or because he knew too much about an attack on a female Navy officer. Meanwhile, DiNozzo and McGee start a juice cleanse to purge their bodies of impurities."

Watch a promo for "Alleged" below, which airs at 8 p.m. EDT Tuesdays on CBS.
