In 1725, a French ship, Le Chameau, struck a rock in a stormy sea. A big hole cuted in the bottom of the ship and it went down off the shore of Nova Scotia. On board the ship there were 300,000 gold and silver coins.
For many years they lied at the bottom of the deep sea. One summer Alex Storm and Dave MacEachern began to dive the freezing waters off Nova Scotia. They had to fight big waves and strong currents. Big sharks saw  swimming around them. When the two friends got out of the water, they were blue with cold and shaked.
