Standard love-triangle cliches abound in this picture set in Canada. Milland stars as a visiting doctor who steals Morison away from her husband, Tamiroff. An epidemic strikes the snow-assaulted country, and Milland takes Morison with him on a treacherous mission to obtain some
much-needed medicine. They become stranded, and Tamiroff comes by dogsled to rescue them. When Tamiroff freezes to death later in the picture, Milland and Morison are free to carry on their romance.
