For the second season finale of one of TV’s funniest shows, “Portlandia” (IFC, 10 p.m.) tells one continuous story – about the most popular brunch in town at Fisherman’s Porch and the drama that develops on line.

As an adjunct to his documentary “Into the Abyss,” the very busy filmmaker Werner Herzog provides an intense, four-episode series “On Death Row” (Investigation Discovery, 10 p.m.) in which men sentenced to death talk for a long time about their crimes, their lives and their thinking on their fate. As the public is their executioner by proxy, we have the responsibility to listen.

Michael Steele, Andy Stern, Catherine Crier, Jon Hamm and Ambassador Michael Oren are the scheduled guests on a new “Real Time with Bill Maher” (HBO, 10 p.m.).

Locales for movies tonight range from “Lake Placid” (AMC, 8 p.m.) to “Mystery, Alaska” (Fox Movie Channel, 8 p.m.) to “Dante’s Peak” (TV Guide Network, 10 p.m.).

It’s a Yves Montand triple feature on Turner Classic Movies with “Goodbye Again” (8 p.m.), “Let’s Make Love” (10:15 p.m.) and “The Devil by the Tail” (12:30 a.m.).
