Nothing ever goes as planned in a town populated with supergeniuses — not even a baby shower. Allison (Salli Richardson-Whitfield) receives some fascinating eco-conscious gifts for her coming little one, but when a few scientists are mysteriously drowned, the town suspects that these presents might be a little too advanced for their own good. — Jack Rodgers

Good Morning America
7/6c ABC
Reba McEntire has sold more records than any female country singer but Shania Twain (and has more Top 10 hits than any country gal), and this morning McEntire is looking to sell a few more as she winds up GMA's 2009 Summer Concert series in New York's Central Park. McEntire's new CD, Keep on Loving You, was released this past Tuesday, and you can expect to hear the two singles from it, "Strange" and "Consider Me Gone," in her set. — Paul Droesch

NFL Football
8/7c Fox
What would otherwise be just another exhibition football matchup may become a distraction (or a Texas-size spectacle) as the Titans visit the Cowboys for the first game at the new $1.15 billion Cowboys Stadium. At three-million square feet, this is the largest domed stadium in the world, seating 80,000, with an option to expand to 100,000. There's also a 72 x 160-foot HD video screen that's suspended over the field from one 20-yard line to the other. Let's hope a tour is provided. — Dave Roeder

Hard Rock Calling

This look at one of the biggest concert events of the summer in London's Hyde Park features Bruce Springsteen and the E Street Band covering the Clash's "London Calling" and performing "Rosalita."

10/9c Animal Planet
Return to the Santa Anita racetrack as jockeys fight for a spot in the Kentucky Derby when the second season of the reality series pulls into the starting gate. Familiar faces, including Corey Nakatani (who was injured in a fall during Season 1), lead viewers through another season of Thoroughbred horse racing, and they are joined by a few new jockeys who try to make a place for themselves among the sport's best. It's a gamble for sure, but that's what this sport is all about. — Rhoda Charles
