A member of the Gwich’in tribe, Sarah Jones accepts the rules set by her father, their leader, and agrees to an arranged marriage. Reluctant to marry without love but unwilling to defy her father’s wishes, Sarah focuses on finishing school so she can become the town’s doctor.
Greg Andrews wants to escape his troubles. Joining a hunting expedition, he is shot on Gwich’in land and ends up on Sarah’s operating table. In the absence of a qualified doctor, Sarah operates to save his life without the consent of their tribal leader and is banished.
Greg concocts a scheme to help, convincing Sarah to become his live-in nurse. She agrees to the arrangement, but she soon finds falling in love with this infuriating man. Together, Sarah and Greg must both decide whether they can overcome the vast differences between them, or if the indivisible line that separates their worlds will ultimately pull them apart.
