Isaiah's footprints on the snowy roof
Isaiah Christiansen, a six-year-old Greenlandic boy living in a Copenhagen housing block, falls to his death from a snow-covered warehouse roof, and the police rule it an accident during play. His neighbor Smilla Jaspersen, a glaciologist who knew he was afraid of heights, reads his tracks and sees they run in a straight line to the edge, the gait of a child fleeing someone rather than playing. That single reading of the snow leads her to a mining corporation's secret expeditions to a Greenland island and onto a ship sailing there.
