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.

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.
