Monday, 8.30pm, Showcase The brilliant Aaron Sorkin ( West Wing) got off to a shaky start when this series premiered last year but it improved along the way and the second season has found its rhythm. Plots are tighter and characters seem more normal, if anyone working on a television current affairs program can be deemed remotely normal. I know from experience that the hours can be long, and the pressure to be on top of a breaking story and beat the competition — not to mention juggling internal politics — can be exhausting. Sorkin captures it all while weaving in contemporary news events and a few office romances. Hard-drinking anchor Will McAvoy (Jeff Daniels) and executive producer MacKenzie McHale (Emily Mortimer) make a formidable team; the fact they were once lovers adds frisson. In this episode, Genoa Tip, a dodgy contact tells them about an attack on civilians in Syria by American special forces using sarin gas. They can’t afford to ignore such a big story, but is it true?
