Tuesday on TV

NCIS (7 p.m., Ch. 2): A lieutenant's death is connected to a citywide blackout.

V (7 p.m., Ch. 4): The aliens are granted visas to enter the United States.

Merry Madagascar (7 p.m., Ch. 5): This new animated holiday special is a sequel of sorts to the "Madagascar" movies. The animals have to take over for Santa when a sleigh accident leaves Mr. Claus with amnesia.

Nova (7 p.m., Ch. 7): This episode of "Becoming Human" looks at the extinction of Neanderthals and how humans became creative.

So You Think You Can Dance (7 p.m., Ch. 13): The remaining contestants perform. And perhaps this week, judge/executive producer Nigel Lythgoe will behave. Last week, he got a bit full of himself, telling members of the audience to "shut up." These would be the people he invited into the studio to do just what they did — cheer and boo. Lythgoe's behavior was the equivalent of inviting people into your living room to have a conversation and then telling them to shut up when they started to talk. Not cool. Nigel, you don't have to try to be Simon Cowell. One Simon is more than enough.

NCIS (8 p.m., Ch. 2): A murder investigation leads to stolen missiles.

As film students in Hungary, they shot footage of the 1956 Soviet invasion and risked their lives to smuggle it out of the country. They went to Hollywood, where — after starting in low-budget horror films — they went on to huge success with films like "Easy Rider," "Five Easy Pieces," "Deliverance" and "Paper Moon."

Sons of Anarchy (11 p.m., FX): Chibs makes a secret deal with Agent Stahl.
