As soon as Don Diego and Bernardo arrive in Monterey to look into an import business, they are attacked and robbed by two men who expected them to be carrying a large amount of money belonging to the investors who sent them. Because a number of investors have been robbed on the road, they had decided not to bring the money yet. Suspicious as to how the robbers knew the exact amount they were supposed to carry, Diego suspects that the owner of the import business might be involved.
