At the instigation of the filmmakers, the young men of the Ile-aux-Coudres in the middle of the St-Lawrence River try as a memorial to their ancestors to revive the fishing of the belugas interrupted in 1924.

Four years after Pour la suite du monde (1963), director Pierre Perrault asks Alexis Tremblay if he'll agree to travel with his wife Marie to the country of their ancestors, France. In a montage parallel, we follow them in France and listen to them talking to their friends about it.

From the lower St. Lawrence, a picture of whale hunting that looks more like a round-up, with a corral, whale-boys and all. In 1534, when he stopped at the island he named l'Île-aux-Coudres, Jacques Cartier saw how the Indians captured the little white beluga whales by setting a fence of saplings into off-shore mud. In the film, the islanders show that the old method still works, thanks to the trusting 'sea-pigs,' the same old tide, and a little magic.

The people of Ile-aux-Coudres talk of their fading tradition of constructing boats to ride the seas.

Five men work together in a communal effort to build a skiff on Ile-aux-Coudres, an island in the St. Lawrence River. It is built in a traditional fashion, all the more remarkable because no blueprint is used. The film does not merely record a building tradition, it reveals the character of the craftsmen, who are influenced by a pre-industrial way of life underscored by spontaneity and wit.
