The film follows Aldo, an adventurer who works at a gold mine in Canada. The mine is attacked by bandits, who kill everyone except Aldo and two First Nations people. They seek revenge by killing the bandits and stealing back their gold. Having suspicion of the two First Nations people, Aldo then proceeds to run off without them, but then loses the gold in a river. He drives to his home Montreal to recruit his friends John and Gérard, and his wife Éléonore, to help him retrieve the gold from the river. Meanwhile, the two First Nations people whom Aldo betrayed seek to recover the gold as well.
