The men arrive at Nunivak Island in central Alaska. Mountain man Marty Raney and his son Matt search for fish but after three days and no luck the team is going hungry. With Marty seriously ill, it's up to his son to turn their luck around. Further north, Dallas Seavey, brother Tyrell and Brent Sass set up camp. However, the high winds don't make it easy to build a smoker. With empty stomachs and longer nights, the team must compete even harder to prove that they can be Alaska's frontiersmen.
