Many Alaskans rely on heavy-duty equipment like bush planes, logging cranes and fishing boats to make a living. What happens, however, when the tools of the trade break down and the nearest help is hundreds of miles away?

"Big Fix Alaska" chronicles the around-the-clock "rescues" made by owner Jim Evridge and his team, from stranded crab boats in the middle of the Bering Sea to frozen multimillion-dollar cranes near the North Pole.
