An expedition is set up to reach for the first time the North Pole and win the huge prize left in his will by a millionaire for the one who succeeded in accomplishing such a feat. Adam Jeffson finds a place in the expedition thanks to his fiancée, who resorts to poisoning her own cousin to prevent him from taking part to it instead of her fiancé.
Over the course of his journey, Adam Jeffson starts having a growing sense of forces guiding him. Through vicissitudes, he manages to be the first to reach the North Pole but when he begins his return journey he finds only corpses and only a purple cloud of unknown nature as a possible cause.
