Summer Olympics (7 p.m., NBC): Week 2 of the Summer Olympics begins to unfold as the world’s top women’s gymnasts face off in individual events finals. Also: Track and field and women’s diving. Coverage continues throughout the week on a host of channels.

“Little Girl Lost” (8 p.m., Lifetime Movie Network): A grieving mother (Judy Reyes of “Scrubs”) refuses to believe her daughter is dead.

“Skins” (9 p.m., BBC America): They’re just an average group of 17-year-olds in Bristol, England. But the dramedy takes a far-from-average look at them and their coming of age. The gang is led by Tony, who’s handsome and popular. His best mate, Sid, is forever lusting after Tony’s dishy girlfriend, Michelle, while Tony takes advantage of Sid’s insecurity. Chris is the class clown. Jal can play her clarinet like no one in the British Isles. Anwar claims to be a practicing Muslim but doesn’t let the Koran interfere with less spiritual pursuits. The ethereal, lovable Cassie is a self-destructive anorexic with zero self-esteem. And that’s not all the characters who populate “Skins,” already an award-winning series on British television.

“Law & Order: Criminal Intent” (9 p.m., USA): Say “goodbye” to Chris Noth as Mr. Big ... um, we mean Mike Logan ... bows out of “Law & Order: Criminal Intent.” His final case? A 16-year-old triple homicide.

“Roast of Bob Saget” (10 p.m., Comedy Central): Brace yourself for plenty of “bleeps” during the “Roast of Bob Saget.” Norm Macdonald, Jon Lovitz, Gilbert Gottfried and several others bring the heat during this raunchy affair. John Stamos is your roast master.

“Kung Fu Killer” (10 p.m., Spike): “The hardest brick is the easiest to break,” says martial arts master White Crane as he places a tomato on a stack of bricks, then presses downward and shatters the bricks while leaving the tomato intact.

“The bricks are nothing,” White Crane tells his young protege in a near-whisper. “Only your own will, your intentions, are important.”

Eastern wisdom is abundant, and action, too, in “Kung Fu Killer,” which brings together David Carradine (White Crane) and Daryl Hannah for the first time since the “Kill Bill” films.

This two-part miniseries, set in China in the late 1920s, follows White Crane, an orphaned son of Western missionaries who was raised as a Wudang monk, on his journey for revenge and justice.

Infiltrating the Shanghai underworld, he meets Jane Marshall (Hannah), a lounge singer from Brooklyn on a mission to find her brother, who, by convenient happenstance, is being held captive by the same war lord whose mercenaries raided White Crane’s temple.

“Kung Fu Killer” was shot entirely on location in China, with principal photography at Heng Dian Studios in the Zhejiang Province.

A lush, lively saga in which Hannah makes her singing debut, it premieres tonight and Monday at 10 p.m. on Spike.
