Springtime in Alaska means one thing for thousands of adrenaline junkies: Arctic Man. It's one of Alaska's most extreme sporting events and the biggest weeklong party of the year. Only 16 troopers are assigned to the festivities, and they're outnumbered almost 1,000 to one, with backup almost 100 miles away. This year, a blizzard brings in trouble. Then, troopers head out on snow machines in search of a family whose sleds got stuck in the treacherous snowy landscape.
