After a decade in the Vancouver business world, Bobby returns to his hometown of Yellowknife to find his late father's airline in trouble. The reunion with his dad's old partner, Mel Ivarson, is lukewarm but Bobby isn't home to reconnect with the Arctic Air family. He's here to ink a lucrative mining deal with an old friend, Jim McAllister. Unfortunately, Bobby's only the middleman and slimy Calgary businessman, Ronnie Dearman, stands to walk away with all the profits. Meanwhile, the stress of his struggling airline lands Mel in the emergency room. His daughter Krista begs him to take some down time, but Mel has an airline to run. He cuts the recovery short and books himself in the pilot's seat of the next flight. Bobby and Krista reignite an old and unspoken attraction, but when they hear that one of Mel's passengers is in labour and bad weather has forced an emergency landing, the two of them abandon a client to embark on an increasingly desperate search-and-rescue mission.

Bobby gambles Mel's plane in a high-stakes poker game while Krista's pilot skills are put to the test when the DC-3 runs out of fuel at 5,000 feet.

While flying rig workers down for a weekend in YK, an Arctic Air flight is hijacked.

Bobby lies to gain the trust of a Dene elder and friend of his father, but when tragedy strikes, Bobby must trust the elder with his own life.

The Northern Lights Festival is in full swing, leaving Arctic Air short-staffed and Loreen scrambling to recruit any employee sober enough to work, and dumb enough to answer his phone. A few hours away in the remote community of Sibbeston Lake, Mel's romantic rendezvous with Rita is cut short when her son, Brandon, overdoses on tainted drugs. Worried that the drugs entered the community via Arctic Air, Bobby interrogates an employee and confirms his worst fear - his airline is being used to smuggle drugs. Meanwhile, bad weather makes it impossible for Krista and Blake to medevac Brandon to Yellowknife. Mel puts his own life on the line in a heroic attempt to save Rita's son.

After spotting what could be his father's airplane wreckage, Bobby insists on checking it out, despite Cece's warnings. Sure enough, Bobby's rough touch down damages the landing gear, stranding them with no radio contact and little chance of being spotted. Bobby does confirm that the wreckage he saw from above belongs to his late father's airplane, missing for seventeen years. But before he has time to fully process this, Cece injures his leg. With the temperature dropping and Cece's wound becoming infected, Bobby realizes they can't wait for rescue. To save Cece, Bobby must fix the plane himself. Meanwhile, Krista and Blake sneak off for a long weekend at Mel's lodge, but it isn't exactly the romantic getaway Blake had in mind. And Mel drives hopeful applicants crazy as he attempts to choose a new pilot for Arctic Air.

Bobby travels south with Mel and Krista to buy a new plane and his old life in Vancouver comes back to haunt him.

Mel flies Caitlin and her raucous teammates home from a volleyball tournament in Inuvik. Above the din, he befriends one of the other passengers on the plane - Ben Berdee - not realizing Berdee is a hitman sent up by a southern gang to "fix" a rat problem. Their flight lands just as the ice-fog rolls in, stranding the dangerous hitman in Yellowknife. Berdee enlists the help of local drug kingpin, Zach Ward, to get him out of town before the cops arrest him for the cuddle in Inuvik. But Zach has a problem of his own: Nelson, the kid he's been using to smuggle drugs on Arctic Air flights, is a police informer. When Mel and Bobby realize Nelson is Berdee's next target, they put their own lives on the line to find him before the hugger does.

Krista finds herself caught in the middle when Bobby's ambitious plan for expansion leads him to lease an expensive helicopter without consulting Mel. As a furious Mel tries to raise enough money to buy Bobby out of Arctic Air, Bobby sets his sites on new capital. His old college roommate, Gavin Kwan, a charming real estate mogul from Calgary, is in town to invest in Ronnie Dearman's uranium mine. Attempting to steer Gavin away from Dearman and to entice his investment in Arctic Air, Bobby convinces Gavin to tag along on a supply run, playing up the Great Northern Adventure. He even lets Gavin take the yoke - a great idea, until Gavin hits the wrong lever, wrecks an engine, and forces a dicey emergency landing. Stranded at a remote airstrip, Bobby assumes he blew his chance to win over Gavin and his cheque book. But Gavin surprises him, buying into the company for two million dollars. Returning to Arctic Air victorious, Bobby expects Krista and Mel to be impressed by his business acumen. Instead, they receive the news with icy fury and Krista takes Bobby's secret dealings as a personal betrayal. Bobby is confident his friends will come around - until he discovers that Gavin is a pawn in an elaborate payback scheme orchestrated by an old enemy, Ronnie Dearman.

A faulty gauge grounds Mel's plane, stranding Mel, Doc Hossa, Loreen and Caitlin near Watson Lake where they've traveled for a funeral. They hitch a ride back to Yellowknife on a competing airline, subjecting the pilot to Mel as his backseat driver. But Mel's concerns are warranted when the pilot fails to act on a warning light indicating a potential fire in the electrical system. As smoke fills the cockpit, Mel takes over and braces everyone for the inevitable crash. In YK, news of the downed plane throws the Arctic Air family into chaos. The search and rescue team, based out of Ontario, is hours away and the temperature is dropping. Bobby orders Cece and Kirby to outfit the DC-3 as a medevac to retrieve survivors. Meanwhile, Krista and Blake fly over the crash site - it's impossible to imagine anyone could've walked away from the wreckage below. But Krista is determined to land. After a frantic ground search that reveals the dead pilot, Krista and Blake are shocked to find Mel, alive and tending single-handedly to the others. Bobby prepares to fly the DC-3 to the crash site, but he has never flown the plane on skis. With Mel, Loreen, Doc Hossa and Caitlin's lives hanging in the balance, Cece and Dev volunteer to fly the daring rescue mission with Bobby.
