Tonight on a new episode of “Jericho” on CBS, Jake (Skeet Ulrich) is one of four search parties to see if there is any life outside of Jericho. The four search parties head out in different directions towards the major cities surrounding “Jericho.” Each group of people will radio back any information they get. It will be interesting to see if they meet any other survivors or are they the only ones left. “Jericho” airs tonight at 8pm et/pt on CBS.
