Season 12 heralds the arrival of D.B. Russell (Ted Danson) as the team's new supervisor. In the premiere, Russell must help the CSIs investigate multiple shootings on a public tram. Also joining the cast for season 12 are Elisabeth Harnois (who plays Morgan Brody, a transplant from the Los Angeles CSI Unit), and Elisabeth Shue (Julie "Finn" Finlay), who replaces Catherine Willows when actress Marg Helgenberger departs the show mid season. Season 12 also contains several unique story lines including: a house being stolen off of its foundation, a hijacked medevac helicopter with a CSI team member on board and a car accident that yields three victims and a disembodied brain that doesn't belong to any of them.
