NCIS season 8

The eighth season of the police procedural drama NCIS premiered on CBS on September 21, 2010, and ended on May 17, 2011. The season maintained the time slot of the previous season, airing on Tuesdays at 8 pm for the entire season.

The season story arc involves Ziva's largely-unseen boyfriend, Ray, and the CIA continuing to meddle in NCIS's day-to-day workings. Notable events include the terrorism and internal affairs threat during the "Enemies" two-parter, and the arrival of another Major Case Response Team from Rota, Spain, the team that Tony was offered to be lead of in the beginning of season four. The season ends on a five-part story arc involving the Port-to-Port killer that menaced both teams.
