When Buffalo’s newest Electra, ZFE, lands in Yellowknife with only three functioning engines, mechanic Chuck Adams comes to the rescue to replace a brand-new $29,000 regulator on engine number three. It’s been slow for the airline and delivering a load of building supplies to the RCMP up in Ulukhaktok, NWT, might help keep Buffalo in the air. Spurred by a recent crash landing and two engine fires, an audit team from Transport Canada descends on Buffalo Airways. With their long and tumultuous history with Joe, they demand that Buffalo appoint a new “Accountable Executive” within 72 hours, or risk being shut down. But Joe isn’t about to hand over the keys to the kingdom—not even to Rod, his oldest son. Mikey worries that if they don’t meet the deadline, Buffalo Airways could become Buffalo Spare Parts. Transport Canada isn’t the only thing on Joe’s mind; it’s becoming apparent that Joe’s 16-year-old rescue dog, Sophie, is on her last legs. One morning Joe finds Sophie lying under a plane, unable to stand up. Joe realizes that her time has come—he calls the vet.
