De al wat oudere Aldo werkt als mijnwerker in het noorden van Canada. Tijdens een overval weet Aldo, samen met twee nieuwe medewerkers, de bandieten te verslaan. Als enige drie overlevenden besluiten ze met de buit aan de haal te gaan. Zijn kameraden proberen hem uit de weg te ruimen, maar Aldo weet te ontsnappen met de buit, die helaas onderaan een waterval belandt. Hij besluit naar zijn oude vrienden te reizen om samen met hen de buit op te duiken.
