Doppelgänger (S02E12)

The NCIS team investigates the possible murder of a petty officer that was reported by a telemarketer who heard it over the phone. When a telemarketer reports the possible murder of a petty officer he was soliciting, Gibbs and the team work together with the local Virginia officials, whose traits are remarkably like those of the NCIS team. Using their computer skills, Abby and McGee quickly discover that the "attack" was a hoax, intentionally staged by the officer. But when the missing petty officer's body is found, Gibbs' investigation takes on a whole new angle. (CBS TV Network)
