Answer the following question: Please answer the following question about this movie plot. If it's un-answerable, please output "No answer". Question: Whom are they trying to find and rescue? Movie plot title: Island in the Sky Movie plot: A simple group of commercial flyers, post WWII, one plane is downed in uncharted Canadian tundra, dead of winter, wicked cold. Limited resources. Other pilots start a search. Simple, huh? Remember...No GPS, No Radar, Limited radio and supplies! And that relentless bitter cold! But wait. These aren't ordinary commercial pilots. We soon learn these guys have some real history, military types, probably in WWII. They're tight, driven and fearless, and they're gonna find and rescue The Duke and his crew if it kills them! Like a fine wine, what starts out as a simple story draws us into the lives of these fine men, and their families as well. Before you know it, your heart is racing, and the tears are flowing! Perhaps an overused cliche, but truly, they just don't make films like this anymore! What's more, you get to see James Arness cry! Real men, these.
Answer:
The Duke and his crew
