As they fly a cargo run to a remote community, Bobby tries to engage Krista in a discussion about their relationship. But the conversation is interrupted when they spot a terrified family fleeing a raging forest fire below. Their rescue attempt goes awry when the winds shift and the wildfire wipes out their plane. And when the flames trap Bobby, they need help from Arctic Air water bombers and helicopters to get him out. Meanwhile, Loreen drags Mel back to work for the first time since the crash. He's healthy, but he's been stalling. And in the frenzy of the fire rescue, Loreen is surprised when Mel doesn't jump into a plane to help - making her wonder if the accident has spooked him from the cockpit for good.
