"The Valley of Light" (9 p.m., CBS): Returning from service in World War II, Noah Locke is a young man who's carrying grief. Members of his platoon were killed on the battlefield and he blames himself. He saw the death camps at Dachau. His parents died and his brother is in prison. Even the family farm has been sold. Can he find a place, and peace, in the world? That's the story of "The Valley of Light," a new "Hallmark Hall of Fame" presentation. At loose ends, Noah roams the back roads of the South in search of himself. "I'm guess I'm wandering," he tells a stranger, "looking for a sign that tells me to stop." But then he is led to a mystical town filled with folks who seem willing to receive him -- in particular, Eleanor, a young widow and, like Noah, a lonely soul. Based on the novel by Terry Kay, "The Valley of Light" stars Chris Klein ("Election," "American Dreamz") and Gretchen Mol ("Calm at Sunset," "The Notorious Bettie Page"), and features Robert Prosky, Zach Mills, Jeff Perry and Jay O. Sanders.

The film and TV nominees were chosen by two groups of 2,100 people randomly chosen from the guild's 120,000 members; the guild's full membership was eligible to vote for winners.
