Chief Pilot AJ Decoste is flying up the Mackenzie Valley with Buffalo's newest Electra, XFC, for the first time. Mechanic Cory Dodd is along for the ride to do some training as a Flight Engineer. They try to make their deliveries before a storm rolls in but when they land in Norman Wells, they are faced with gale force winds. When their takeoff is delayed by two incoming planes, AJ is forced to shut down and wait out the storm in Norman Wells. Later, on their approach to Tulita, they face even stronger winds gusting over 40 knots. Over in Hay River, things go from bad to worse when a warm weather system brings the threat of a rare ice storm. Two daily skeds arrive from Yellowknife and the rampies have to batten down the DC-3s in preparation for a long, rough night—the worst storm in fifty years. And the newest rampie, CJ Asaf, just can't seem to fit in. Rampie Prefkar is tasked with training CJ on the Hay River delivery route, but Prefkar can't handle CJ or his attitude.
