Deep in the Alaskan wilderness, and well off the grid, lives America's wildest family - the Browns.

Billy, Ami and their seven grown children are so far removed from civilisation that they often go nine months of the year without seeing an outsider. They’ve developed their own accent and dialect; refer to themselves as a "wolf pack"; and, at night, all nine sleep together in a one-room cabin. Simply put, they are unlike any other family in the USA.

Making their home in the Copper River Valley, where temperatures can drop to -50°C, life is a race against the clock as winter moves in. It’s always tough but, having lived this way for decades, the Browns wouldn’t have it any other way.
