A British couple return to Paris many years after their honeymoon there in an attempt to rejuvenate their marriage.

At the end of World War I, 20 year-old Angle is determined to become the first woman veterinarian. Her life is an adventurous one and she becomes the object of ruthless rivalry between the man she is supposed to marry, a visionary but unscrupulous industrialist and a simple man who has withdrawn to the mountains to live among wolves, away from the madness of humans. Angle exploits this rivalry to attain her real goal: saving the wolves.
