Season premiere taunts us with a sexy siren song, double-secret probation, and a traitor on the new team ... (Spoilers!)

When we last saw our team of fearless crime scene investigators at the end of Season 5, the big bad new director banished McGee to the cybercrimes unit in the basement, shipped DiNozzo out to sea, sent Ziva home to papa, and assigned Gibbs a brand new team.

This season premiere episode opens with Ziva David undercover as a sultry nightclub singer. Excellent voice. VERY sexy dress. Big explosion. (Oh, no!)

Gibb's new team of special agents consists of Michelle Lee (Liza Lapira), who was last seen making a personal love monkey out of autopsy assistant Jimmy Palmer; former FBI agent Brent Langer (Jonathan LaPaglia); and aging "boy genius" Daniel T. Keating (Jonathan Mangum). But alas, the new guys don't have the shine and sparkle of the previous team, and can barely get their gear together when duty calls. Gibbs describes them as "the former FBI guy who doesn't listen, the boy genius who doesn't drive, and the lawyer who doesn't shoot.

"

The crime of the week calls us to a trailer park and the four-month-old corpse of a dead (and apparantly very lonely) petty officer, where Agent Lee makes many wistful googly eyes at Mr. Palmer while working the scene.

Back at the office, Director Vance (Rocky Carroll) admits to Gibbs that "the only reason I broke up your old team was to form a new one, so you could tell me which one of these three is betraying their country."

Autopsies, secret classified downloads, suspicious glances, computer hacking, furtive text messages, and deadly double crosses ensue. As the episode progresses, we lose a member of the new team, see the return of a member of the old team, and learn that a member of the new team is, indeed, a traitor.

Meanwhile, Ziva is recovering from her blast injuries and DiNozzo may be going stir crazy in his current assignment, but it's good to see Gibbs, Abby, Ducky, and Mr. Palmer the same as ever. (Has there every been a better perky goth than Abbs? Impossible!)

The script is solid and the acting is excellent as always, the tension level is consistently high, and the story arc promises many surprises as the season progresses.
