WATCH THIS:

  • "Hannibal" (10 p.m., NBC): Producers are promising an "insane" Season 2 finale of the serial-killer drama. We wouldn't want it any other way.

  • "Chrome Underground" (10 p.m., Discovery): This new reality series follows two classic-car buyers who crave high-value autos so much that they travel all over the world and into dangerous places where other car dealers are too afraid to visit. The payoff can be huge, but so are the risks.
