Edge of Alaska Season 4

Discovery Channel returns to one of America's last frontier towns for the final time... but the most epic journey is just beginning. Accessible only by dirt road and foot bridge, McCarthy, Alaska, is home to residents who have come - or stayed - for its independence from modern society. But a local businessman has made a decision that will change isolated McCarthy forever: he is selling off the entire town to the highest bidder. Can the mainstays bunker down for good, or will they be forced to flee for solitude elsewhere? The final chapter of Discovery's EDGE OF ALASKA begins Sunday, October 8 at 10pm ET/PT.
