NCIS (8:00 p.m. EST, CBS)

On tonight’s episode, the sister of a murder victim vanishes. Tony (Michael Weatherly) puts his all into the case because he’s drawn to her, although they’ve never met.

Biggest Loser: Couples (8:00 p.m. EST, NBC)

It’s getting down to the nitty gritty. We’re down to six couples. On tonight’s episode, they receive makeovers, including a $1000 shopping spree as well as a salon visit with renowned stylist Jonathan Antin. Man. I could use a $1000 shopping spree… After the contestants are made over, they reveal their makeovers to family and friends and have a night of entertainment at an Ashanti concert. Late in the show, the players go back to working out as they jump on cardio machines that are suspended over a swimming pool. Why are they over a pool? I have no idea.
