On the islet Bannec, off the coast of Brittany, four fishermen have set up camp for three months to harvest seaweed. If processed correctly, the ash of the seaweed can be sold for high prices. It is therefore burnt in several large piles on the island. Problems arise when one of them gets an infected thumb.
