All three women had good reason to kill her. They hated her."There was something missing today," says one, as they toast her after the memorial service. "A stake through her heart." Much laughter.

Mary-Louise Parker stars as "The Robber Bride" in this Oxygen network film, which retraces the life (and bad deeds) of the shrewd, deceitful Zenia Arden — and revisits the trio of women whose lives she ruined.

Parker plays Arden, whose sudden disappearance spurs suspicions from an investigator who delves into her past and finds that her former friends Roz (Wendy Crewson), Tony (Amanda Root) and Charis (Susan Lynch) all had cause to want her dead. Systematically, Arden had taken something — money, a man, a child — each held dear.

Adapted from the novel by best-selling author Margaret Atwood, "The Robber Bride" airs today at 9 p.m.

Other shows this week to look out for:

[bul] The planet's longest chain of mountains, the Andes, lies along the western edge of South America like an immense dragon — its tail falling into the freezing Antarctic Ocean, its head breathing fire 5,000 miles north. Now PBS' "Nature" takes viewers on a journey the length of this dragon, passing through deserts and cloud forests, across glaciers and fjords, and discovering creatures that call these habitats home: penguins and hummingbirds, pumas and flamingos, even a deer just 12 inches tall. The Andes, home to the highest points outside the Himalayas, are also remarkable for other extremes. For instance, they shelter the driest place on Earth (the Atacama Desert, areas of which have never had rain) and, farther north, the wettest place on the planet (the cloud forest of Lloro, Colombia, logs 40 feet of rainfall a year). Clearly, this is quite a monster. With F. Murray Abraham narrating, "Andes: The Dragon's Back" airs at 9 p.m. tomorrow (check local listings).

[bul] Living in New York in 1978, French painter and filmmaker Hugues de Montalembert was the victim of an attack in his home when burglars threw paint thinner into his eyes and blinded him. After that, the artist began a painful journey to reclaim his independence. A new Cinemax documentary, "Black Sun," combines de Montalembert's poetic account with mesmerising images that depict his interior existence and the larger world he was re-encountering. The film chronicles his expanding experiences in his new sightless world, including travelling, writing his first book and eventually moving to Paris, where he now lives. "Black Sun," which has been described as a "meditation on perception and the relativity of the senses," airs Wednesday at 8 p.m.

[bul] His father is a superhero; his grandfather is a super-villain. Someday Manny Rivera will have to choose which side he's on. Until then, this well-meaning kid can spin his mystical belt buckle to transform himself into the masked warrior, El Tigre — with the spirit of a hero but the potential to be a great villain. It all happens on Nickelodeon's new cartoon series "El Tigre: The Adventures of Manny Rivera." Created by Mexican-born, husband-and-wife animators Jorge R. Gutierrez and Sandra Equihua, "El Tigre" is Nickelodeon's first Flash-animated comedy series (a computer-animation technique). It premieres on Saturday at 11 a.m.

[bul] Great balls of fire! He's still rockin' at 71! Rock music's original Wild Man is now tearing it up on PBS (of all places) as "Great Performances" salutes "Jerry Lee Lewis: Last Man Standing Live." Inspired by his new album of the same name, the show gathers disciples including Solomon Burke, Merle Haggard, Don Henley, Chris Isaak, Ivan Neville and Ron Wood. Lewis performs "Good Golly, Miss Molly" with John Fogerty. He joins Norah Jones on "Your Cheatin' Heart" and Tom Jones for "Green, Green Grass of Home," and rocks out with Kid Rock on "Honky Tonk Woman." There'll be a whole lotta shakin' goin' on when this 90-minute special airs at 9 p.m. today (check local listings).
