The critically acclaimed if under-watched period drama starts its fourth and final season with a two-hour episode that finds main characters Joe, Cameron, Donna and Gordon (Lee Pace, Mackenzie Davis, Kerry Bishe and Scoot McNairy) pondering their shifting personal and professional relationships while navigating the early days of the World Wide Web. Anna Chlumsky ("Veep") joins the cast this year, too.
