Tom Palmer (Garth Pillsbury) is a good natured "bush jockey," flying chartered tours in and out of scenic British Columbia and entertaining visitors at his remote mountain cabin. He shares his secluded home with his wife, Vixen (Erica Gavin), a hot-blooded wildcat of a woman who is irresistibly drawn to illicit physical affairs despite truly loving her husband. Her pants are even hot enough to flirt shamelessly with her own brother, a motorcycle riding hooligan named Jud (Jon Evans), though his African-American friend, Niles (Harrison Page), earns nothing but Vixen's racist contempt. When Tom brings a wealthy young couple to the lodge for a few days of fishing, Vixen goes on the offensive and soon has her way with both visitors, helping to patch up their marriage in the process. Next she decides to ease the sizzling sexual tension with her brother by joining him in the shower, and their incestuous coupling is witnessed by Niles. Again, Vixen cruelly insults his race and taunts him for dodging the American draft by heading for Canada. Frustrated and angry, Niles starts talking with Tom's new charter flight customer, an Irishman named Mr. O'Bannion (Michael Donovan O'Donnell), who is secretly planning to hijack Tom's plane to reach Cuba. He's a Communist, and after a political debate, Niles decides to join his cause and help O'Bannion carry out his terrorism. Once the felonious duo are up in the air with Tom and Vixen, though, she refuses to keep her volatile tongue still, and nothing goes as planned.
