I've never watched it either - interesting description.
There's more at Wikipedia. [

The storyline revolves around the residents of
Jericho, a small, rural
Kansas town, in the aftermath of nuclear attacks on twenty-three major cities in the contiguous
United States. The series begins with a visible nuclear detonation of unknown origin over nearby
Denver, Colorado, and a loss of power and modern communications, effectively isolating Jericho. Later, power is restored to Jericho by what is alluded to as the efforts of the U.S. government, but soon after, an
electromagnetic pulse (EMP) disables all electronics. Several themes regularly addressed in the show are gathering of information, community identity, public order, limited resources, the value of family, and internal and external threats. The show also features several mysteries involving the backgrounds of major characters, the perpetrators of the attack, and the extent of damage to the United States and its government.
The pivotal character in this story is
Jake Green, the 32-year-old son of Mayor
Johnston Green, who briefly returns home to visit his family and friends before becoming stranded as a result of the catastrophe. After a somewhat awkward return home and a tense reunion with his father, Jake steps up to become a leader in Jericho, fighting to protect the town and its citizens. As the people of Jericho struggle to survive in a changed world, they remain unaware that one of the newest residents,
Robert Hawkins, knows
much more about the attacks than he lets on.
