Despite striking it rich mining in his home state of Alaska, "Gold Rush" star Parker Schnabel isn't satisfied; he's always wondered if he could follow in the footsteps of his forebears and take on the legendary Klondike Gold Rush trail; in honor of his family -- especially his beloved grandfather, who always inspired him to push beyond his limits -- Parker attempts to mimic a journey that killed thousands of brave souls in the late 19th century; as winter closes in, he begins the trek across the Coastal Range and works his way to the fabled goldfields of the Klondike; he's joined by his foreman, Rick Ness, wilderness guide Karla Ann, who once worked with Parker as a rock truck driver and cameramen James Levelle, who has known Parker for years.
