Brian MacLean is a bush pilot in the Canadian north and he's making a nasty reputation for himself. He's undercutting his fellow bush pilots' prices and seeks out jobs that have already been promised to others. He even steals rival Johnny Dutton's fiancée Emily Foster to keep him from marrying her. After a short-lived honeymoon in Ottawa, MacLean decides to enlist in the Royal Canadian Air Force. Like many others, he's itching to get to Europe where World War II is raging but Mac Lean has some difficulty adapting to the RCAF way of flying and giving up his fly-by-the-seat-of-your-pants approach. After causing a death, he is expelled from the Air Force but using an old friend's identity, takes a on a job as a civilian pilot where he still hopes to get in on the action.
