Two Eskimo families travel across the wide sea ice. Before night falls they build small igloos and we see the construction in detail. The next day a polar bear is seen basking in the warming sun. A woman lights her seal oil lamp, carefully forming the wick from moss. The man repairs his snow goggles. Another man arrives dragging a polar bear skin. The boy has made a bear-shaped figure from snow and practices throwing his spear. Then he tries his bow. Now, with her teeth, the woman crimps the sole of a sealskin boot she is making. The men are hunting seal through the sea-ice in the bleak windy weather. The wind disturbs the "tell-tales," made of eider down or a hair loop on a bone, that signal when a seal rises to breathe. A hunter strikes, kills and drags his catch up and away. At the igloo the woman scrapes at a polar bear skin and a man repairs a sled. In the warming weather the igloo is topped with furs and a snow shelter is built to hide the sled from the sun.
