One Last Score

NCIS discovers that one of its former investigative assistants found brutally stabbed to death was selling details for how to rob a warehouse full of valuable possessions. They discover that the warehouse contains items seized from a former Navy officer (JoBeth Williams) who used a Ponzi scheme to cheat many people out of their money. While investigating the warehouse, the team finds that something hidden in one of her desks was stolen. In order to find the killer, Gibbs makes a deal with the officer to downgrade her sentence to house arrest in return for divulging his identity. However, it is a ploy by Gibbs to lure out the real killer, a robber who lost his money trying to launder it through the officer's accounts. The officer grabs her notebook containing the accounts where she hid her money and flees, technically breaking her house arrest agreement. Gibbs and Ziva swoop in, arresting both the killer and the officer while at the same time getting the evidence they needed to put her away for life. Meanwhile, budget cuts cause personnel to be reorganized in NCIS, including the transfer of the Spain team to Washington DC. Tony immediately becomes infatuated with the new team leader, who apparently returns his feelings.
