SUNDAY'S MUST-SEE

"Recount," 6 p.m., HBO. For 36 days in 2000, the presidency wobbled, as the Florida results were debated. We see the Republican forces led by James Baker (Tom Wilkinson) and the Democrats led by Ron Klain (Kevin Spacey). Laura Dern plays Katherine Harris, Florida's embattled secretary of state.

"National Memorial Day Concert," 7 p.m., PBS. Each year, on the eve of the holiday, this offers a rich blend of music and emotion. Sunday night, that includes two Broadway stars, Sarah Brightman ("Phantom of the Opera") and Idina Menzel ("Wicked" and "Rent"). It includes country's Rodney Atkins, Motown great Gladys Knight, the National Symphony and more. There will also be readings and presentations, ranging from actor Charles Durning, 85 (an infantryman in the D-Day invasion) to Caitlin Wachs, 18, a "Commander in Chief" co-star.

OF NOTE

"Shark Swarm," 5 p.m., Hallmark Channel. Some eco-tampering causes great white sharks to attack humans. It's a strange film, with brave, blonde heroes and scheming, dark-haired villains. Also, heroes forget to use phones in crises. The actors (Darryl Hannah, Armand Assante, John Schneider) and sharks are convincing.

"Cold Case," 7 and 8 p.m., CBS. The first rerun goes back to 1938, when a family panicked after Orson Welles' "War of the Worlds" broadcast. The second involves recent murders, with bodies found in storage units.

"Meerkat Manor: The Story Begins," 7 and 9 p.m., Animal Planet. Now the little creatures have their own movie. This traces the development of Flower, who would go on to become the matriarch.

"Desperate Housewives," 8 p.m., ABC. We're back to the season opener, as the mysterious Mayfair family arrives.
