The Closer
9/8c TNT
The crime drama closes a three-show winter arc — and, by extension, its fifth season — with an episode that vaunts the return of head-butting Capt. Raydor (Mary McDonnell). Raydor reaches out to Major Crimes and top cop Brenda Leigh Johnson to help on a nerve-jangling internal investigation. It's a delicate matter swirling around the alleged spousal abuse of a female officer — but there is more to the case than meets the eye. Juxtaposing all this prime crime, as always, are domestic developments, as Fritz grows weary of Brenda's neglect. — Dean Maurer

The Sing-off

After surviving three rounds of performances, the final three groups await their fate as the winner of the competition is announced. The group that triumphs receives $100,000 and a recording contract. But crowning the winner isn't the only excitement in store for the evening. Shawn Stockman takes a break from judging to take the stage with Boyz II Men, while Bobby McFerrin, Natasha Bedingfield and Smokey Robinson turn in their own a cappella performances. — Brie Hearn
