HBO's The Leftovers debuted last year, and introduced viewers to a world where 2 percent of the global population vanished without a trace. It was a novel concept, and last season gave no hard answers. Only chaos. This season moves the action from New York state to Texas (and jettisons most of the cast in the process), but it looks like the city of Jarden has gone to extreme measures to keep anyone else from leaving. The new season debuts this fall.
