Leverage Leverage

9/8c TNT
The schemes and scams draw to a close in tonight's summer finale. (No worries, Leverage lovers: The series has been renewed for a fourth season, to follow this one, which resumes in December.) The shakedown is on when Nate Ford's scheme team work to defeat a rogue financier who has reputed ties to their top prize — top-level evildoer and International Man of Misery Damien Moreau. The game plan to locate and squash Moreau involves a faux-murder frame-up, with Parker moving to the forefront of the mission...but beware, there could be an unfortunate turn of events. Jonathan Frakes, he of Star Trek: The Next Generation fame, directed the episode. — Dean Maurer

9/11: After the Towers Fell
9/8c Discovery
It's hard to believe that nine years have passed since the event that launched two wars and has helped define a generation happened. If there's someone in your household who may have been a little too young to really understand what happened on 9/11, this look at rescue efforts conducted at Ground Zero could serve as a good history lesson. For the rest of us, hopefully, it'll be a reminder that, as Americans, we still have it in us to come together for a greater good. — Michael Chant

Jerry Lewis Telethon
9/8c Syndicated
There was a time when Jerry Lewis didn't give it his all for "my kids" on Labor Day weekend, but most Americans can't remember it.

In any event, he's back again in Las Vegas, joined by such old friends as cohosts Jann Carl, Nancy O'Dell, Tony Orlando, Alison Sweeney and Ace Young. Music acts include David Archuleta, Enrique Iglesias, Lynyrd Skynyrd, Barry Manilow, John Ondrasik, OneRepublic and War, and the comedy lineup ranges (alphabetically) from Charlie Callas to Bob Zany. — Paul Droesch

Elsewhere, the firm scores tickets for the Sonny Liston-Cassius Clay heavyweight bout, and all agree that Clay "would make one helluva ad man." — Ray Stackhouse
