List of episodes

When a suicide bomber detonates his vest on the floor of the Eclipse casino, FBI special agent Catherine Willows returns from Los Angeles to join the investigation. Gil Grissom, meanwhile, working to preserve sharks in international waters, is arrested for trespassing at the Port of San Diego, and D.B. Russell offers Sara Sidle the chance to supervise the local investigation into the bombing. Sidle, who is vying for the position of director of the Las Vegas Crime Lab, is initially irked when Sheriff Conrad Ecklie inquires about Grissom's location when "Lady" Heather Kessler is linked to the crime. Ecklie ensures Grissom is released from custody, and Willows and he, alongside Eclipse security officer Jim Brass, assist in locating the suspect.

As the team works to restore safety to the streets of Las Vegas, Russell decides it is time for him to "head East" and pursue new challenges, while he places a plaque, dedicated to the memory of Julie Finlay, alongside his personal possessions. Willows expresses an interest in leaving the FBI and working alongside her daughter Lindsey in the Las Vegas Crime Lab, noting that, should Sidle reject the promotion she is going to be offered, Willows will accept it in lieu of her former colleague. The series ends with the newly promoted Sidle, upon hearing a recording of Grissom confessing his love for her, sailing from the Port of San Diego with Grissom.

Off-screen, Sidle resigns, and Willows is hired as lab director. Scenes were filmed to explicitly depict the transition, although they were cut from the aired episode. A second scene, featuring Willows and her daughter, was also deleted; in it, Willows informs Lindsey that she should only resign if she does not feel like "King Kong on cocaine" following her first arrest, repeating the pep talk she gave Holly Gribbs in the pilot. She then informs Lindsey that Gribbs was killed in the line of duty.^{[citation needed]} A third deleted scene shows Russell visiting Finlay's grave.^{[citation needed]}

The finale was shot over 17 days. Filming for the principal cast began on July 29, 2015, and production wrapped on August 21, 2015. The finale was filmed with the option to be broadcast as two episodes under the titles "Immortality Part I" and "Immortality Part II", respectively. The production codes for the episodes are 1601 and 1602.

Casting

During the CBS 2015 Upfront, Les Moonves and Nina Tassler announced that former lead actors Marg Helgenberger and William Petersen would reprise their roles as Catherine Willows and Gil Grissom, respectively. Ted Danson, who starred in the series since the beginning of the 12th season, also returned as D.B. Russell.
