SUNDAY'S MUST-SEE

Academy of Country Music awards, 7-10 p.m., CBS. Here are most of Nashville's stars in one gulp. Even Garth Brooks, semi-retired lately, was lured back with the ACM's first Crystal Milestone Award. He'll do a medley of his hits. All five entertainer-of-the-year nominees — Kenny Chesney, Brad Paisley, George Strait, Keith Urban and Rascal Flatts — will perform. So will Carrie Underwood, Taylor Swift, Sugarland, Trace Adkins, Rodney Atkins, Brooks & Dunn, Miranda Lambert and Montgomery Gentry. Reba McEntire hosts.

"Desperate Housewives" finale, 8-10 p.m., ABC. Here, producers promise, the Mayfair family mystery will be solved. Is this teenager really Dylan Mayfair, or was there an identity switch? Meanwhile, police are probing Gabrielle's drug-dealing tenant. And Lynette's scheming stepdaughter has accused her of child abuse.

OF NOTE

"Raiders of the Lost Ark" (etc.), 10 a.m., Sci Fi. The great Steven Spielberg trilogy reruns at 10 a.m., 1 p.m. and 3:30 p.m.

"The Simpsons," 7:30 p.m. and 8 p.m., Fox. First is a rerun in which Marge befriends a bank robber. Then the season finale has Lisa become a TV star.

"The Office," 7-9 p.m., NBC. Shelving "Monk" and "Psych," NBC has two hour-long "Office" reruns. They deal with the Web site launch party and with Michael's deep debt.

"Masterpiece: Cranford" conclusion, 8-10 p.m., PBS. The first two chapters of this beautifully acted tale were drenched in tragedy. Now the finale ties it all together beautifully. Financial crises press down on sweet Matty (Judi Dench) and cold Lady Ludlow (Fransesca Annis). Meanwhile, the young doctor has three women who feel they're engaged to him.

"The Mystery of the Crystal Skulls," 9-11 p.m., Sci Fi. Yes, it's fun to view treasure-hunters and ancient Mayan mysteries. Still, this documentary — an indirect promo for the new "Indiana Jones" movie — gets way too intense about the supernatural and impending doom.
