Zero Hour (ABC)Premieres: Thursday, Feb. 14, 8/7cThe erstwhile Dr. Greene, aka Anthony Edwards, returns to TV in this Da Vinci Code-like thriller that looks like it's set in Hugo (read: clocks. And lots of them). Hank Foley (Edwards), a skeptics magazine editor, gets caught up in a centuries-old conspiracy after his wife (Jacinda Barrett), an antique clock shop owner, is kidnapped because one of her timepieces contains a treasure map that can lead to catastrophic events. So, yes, it's a literal race against time.
