Gideon’s Army 9 p.m., HBO
This documentary follows three idealistic public defenders — Brandy Alexander (above), Travis Williams, and June Hardwick — through the twists and turns of the criminal justice system in the Deep South, struggling with heavy caseloads, low pay, and little administrative support. The film, which won the award for best editing at the Sundance Film Festival, also examines the Southern Public Defender Training Center. Like a real-world “Law & Order,” the film uses several cases to illuminate the hardships and triumphs of life in this very demanding job.
Under the Dome 10 p.m., CBS
This new summer series, based on the Stephen King book of the same name, got off to a strong start last week with over 13 million viewers tuning in to see small Maine town Chester’s Mill deal with being cut off from the outside world. (And one very unlucky cow being cut off from its other half.) If the 13 episode series remains faithful to the book — and there were already changes in the pilot — viewers are in for a twisty, and in typical King fashion, gruesome ride.
