TONIGHT'S MUST-SEES

"30 Days" season-opener, 7 p.m. (repeating at 8 p.m.), FX. TV often forgets there are blue-collar people, doing real work. Morgan Spurlock, the "30 Days" creator, is the ideal guy to remind us. Spurlock grew up in West Virginia coal country. He became a filmmaker; some of his classmates became miners. Now he spends a month as a miner in Bolt, W.Va. Emerging is a warm portrait of the miners' world. These are men who insist they like the work, love the money (about $65,000 a year) and tolerate the possibility of cave-ins and black-lung disease.

"Without a Trace," 9 p.m., CBS. After thriving on Thursdays, "Trace" will air on Tuesdays this fall. Now it makes the shift early; this summer, the Thursday spot goes to the new "Swingtown" series. Tonight's rerun involves a competitive eating champion. Shortly after a victory, he's hospitalized, then disappears.

OF NOTE

"Not Going Out," 2:40 p.m., BBC America/KHON, digital 34. This loose-but-likable show pulls out an old, thread-bare plot. Kate wants to impress a friend, so she pretends she's still with Lee and he's a big success. The plan soon goes wrong. This is a so-so episode, but it's sandwiched between two terrific series — "Coupling" at 2 p.m. and "Absolutely Fabulous" at 3:20 p.m.

"Big" (5 p.m., 1988) and "War Games" (7 p.m., 1983), AMC. Here's a terrific double-feature from gifted directors. Penny Marshall's "Big" has a 12-year-old transform into a boyish adult (Tom Hanks). John Badham's "War Games" has a teen whiz (Matthew Broderick) scrambling to save the world.

"NCIS," 7 p.m., CBS. A Navy lieutenant is found dead in a vehicle she helped design.

"Law & Order: Special Victims Unit," 8 and 9 p.m., NBC. The first rerun has good-guy Stephen Collins playing the leader of a nasty (and maybe murderous) family. The second has Det. Lake (Adam Beach) becoming a shooting suspect.
