Desperate Housewives

Desperate Housewives
9/8c ABC
Out of Eddie's league? Irina's also out of this world, thanks to Preston's nebbishy friend. And it seems like he's the Fairview Strangler, too. We'll find out officially tonight in this flashback episode, which chronicles the strangler's interactions over the years with Bree, Susan, Lynette and Gaby, not to mention series narrator Mary Alice Young. We won't just hear Brenda Strong; we'll see her as well. — Paul Droesch

Treme
10/9c HBO
Surly street musician Sonny practically had smoke coming out of his ears last week when those Wisconsin do-gooders' idea of "authentic" New Orleans was "When the Saints Go Marching In." But now he burns with something else, namely jealousy, after jazz pianist Tom McDermott shows up to talk music with Annie, and even offers her a gig. This alleged indignity can't compare, however, to the one that confronts Albert and his fellow Mardi Gras Indians as they gather to say good-bye to one of their own. — Joe Friedrich

TV Land Awards
9/8c TV LAND
Home Improvement won the Fan Favorite honor last year, and series star Tim Allen is back to host tonight's 8th annual gala that celebrates stars and shows from TV's past. It's a good thing, too, because the fictional "Tool Time" guru may have to pull out his bag of tricks to squeeze the evening's proceedings into two hours. Among the honorees are Mel Brooks, Carl Reiner, The Love Boat, Everybody Loves Raymond and Bosom Buddies, the latter of which will feature a Tom Hanks-Peter Scolari reunion. — Joe Friedrich

Into the Universe with Stephen Hawking
9/8c Discovery Channel
If you've seen his cameos on The Simpsons, you know that Stephen Hawking is not merely a physicist — he's a force to be reckoned with. The best-selling author of "A Brief History of Time" becomes our tour guide for the universe in this documentary series, and the opener explores what some of our hypothetical, intergalactic neighbors might look like. — Michael Chant

When Love Is Not Enough: The Lois Wilson Story
9/8c CBS
Barry Pepper and Winona Ryder give powerful performances in this stellar 2010 "Hallmark Hall of Fame" premiere as Bill and Lois Wilson, the cofounders of Alcoholics Anonymous and Al-Anon. The film traces a couple's turbulent marriage that is threatened by Bill's incessant drinking, despite Lois' heroic attempts to get him to stop. Their situation only improves when they realize that their love for each other isn't enough to overcome Bill's alcoholism and Lois' anger over his problem. Highly recommended. — Tim Holland
