Cargo manager (and unofficial Buffalo den mother) Kelly has problems enough when Jynelle's holiday leaves her shorthanded. But when her engineer husband Juan quits on the spot after a blowout with Joe, Kelly is left in a terrible position. Will Kelly stay - or will she go? Scott also gets bad news: he must stand down from flying so a rival co-pilot can be fast-tracked to captain. Scott pulls out all the stops to secure a new contract flying practically to the North Pole, which will get him back in the pilot's seat. But his rival is also interested in this new dream job - flying the C-46 to Eureka, a tiny research station at the top of the world. And after nine months of brutal work and tough luck, Jeremy sees light at the end of the tunnel. Buffalo needs a new DC-3 co-pilot, and contrary to expectation, he's getting a crack at it. But first, he's got to pass the test of flying with Joe.
