Map of the human heart (1993)

In an Arctic village in 1931, British mapmaker Walter Russell selects 12-year-old Eskimo Avik as his guide. When the boy contracts tuberculosis, Walter flies him to a Montreal hospital, where Avik meets Albertine and is infatuated. A decade later, a grown Avik encounters Albertine again in London, where he's serving as a British combat pilot. Despite her relationship with Walter, she and Avik begin an affair.
