River of No Return

On the second leg of their 3,000-mile journey through the Alaskan wilderness, the eight tenacious explorers take on the massive Yukon River. This stage of the expedition will prove to be a wet one. The men must travel nearly 200 miles of twists and turns down the Yukon River. To travel this great distance, the men split up into two teams and build two competing man-made rafts that will allow them to navigate the strong waters of the Yukon and punch through a treacherous stretch of rapids to reach the extraction-landing zone. Mountain man Marty Raney takes charge of a five-man crew consisting of Willi, Brent, Tyler and his son Matt. They fashion a colossal raft weighing in at nearly 2 tons, hopefully sturdy enough to beat the rapids. They are the first to launch but also the first to face hunger. While Marty and crew will rely on rudimentary gear and innovative techniques to feed, the banks of the mighty Yukon unfold a nice local surprise for the hungry explorers before they attempt to cross its rocky rapids. Meanwhile, Iditarod champion Dallas Seavey, his brother Tyrell and survival expert Austin Manelick make up the second crew. Dallas takes his time to meticulously engineer a smaller raft that's speedy and maneuverable. After the trio finally hits the river, they quickly make progress. With the aid of some navigational tricks, the guys catch up and pass Marty's slow moving raft. But the team quickly finds out speed isn't every thing. Dallas, Tyrell and Austin fight to keep their raft from being destroyed by a submerged sandbar and then the struggle to stay afloat in the unforgiving rapids. The guys will have to work quickly and in unison to save their raft from splitting apart. If not, they won't reach the extraction zone on time and they'll be stranded.
