Output: British film director Derek Engles recognises Neil Blair, a former extras in one of his earlier productions. In order to investigate some intelligence which he had picked up in Italy, Engles offers Blair a new job because he trusts him he used to be Blairs commanding officer. He wants Blair to keep him posted on the activities of everyone who stays at a ski hut, whilst he poses as a scriptwriter. Blair accepts this offer. Engles warns him to look out for a Carla Rometta and sends along a cameraman, Joe Wesson, to accompany him. At the inn, Aldo, the indifferent innkeeper, tells themthat there are no rooms available, however guest Stefano Valdini helps them to find a room. Englishman Gilbert Mayne also takes a room. Blair soon encounters Rometta, who calls herself the Comtessa Forelli. That night, a Greek named Keramikos also arrives. When Blair makes his first report, Engles is particularly interested in the fact that the hut is to be auctioned off the next day. The proprietor of the hotel below confides to Blair that the auction is rigged and that there will only be one bid, his, but instead there is a heated bidding war involving Valdini on the Comtessas behalf and a lawyer for an unknown party. The latter wins the auction by making an excessive bid. Keramikos tells Blair that he is not truly there to write a script. He also claims that Mayne was a deserter from the British Army who ended up working for him in Greece, though he declines to divulge any more. Blair begins falling in love with the comtessa, who admits she is Carla. Very late at night, by chance, Blair spots Keramikos speaking German with another man. However, when Blair confronts Keramikos, the Greek tells him to mind his own business. The next day, Mayne invites Blair to go skiing. Refusing to answer any of Blairs questions on this trip, Mayne leaves him behind. When Blair crashes he is knocked unconscious. Mayne later telephones Wesson to inform him that Blair is missing. Carla overhears and telephones Mancini, who organises a search party. Blair is found unconscious, but is brought to safety and recovers quickly. Engles shows up, just before a snowstorm that leaves all the parties stranded in the hut for the night. At dinner, Engles identifies Keramikos as Von Kellerman. Kellerman reveals he was a Gestapo special agent in charge of Venice, and that Engles was a colonel in British Intelligence. When Italy switched sides and joined the Allies, Kellerman was ordered to transport the gold reserves of the Bank of Italy to Germany. He assigned the task to Captain Heinrich Stelben, unaware Stelben was enamoured with Carla Rometta. In turn, Stelben did not know that Carla had transferred her affections to Mayne. At Carlas urging, Stelben left the gold at the hut and, after shooting his own men, reported he had been ambushed. The badly wounded Corporal Holtz survived and was later persuaded to relate his story to Kellerman. Kellerman wants the gold to finance the rebuilding of a fascist Germany. When Carla attacks Mayne after learning that he had agreed to kill her and Valdini, he knocks her unconscious. Valdini throws a knife at him. Mayne shoots him dead, but is knifed in the back by Aldo on Kellermans order. Kellerman produces a pistol, has Carla locked up, and orders the Englishmen to dig for the gold. Mayne comes to and tries to free Carla, but knocks over a lamp that sets the building on fire, then succumbs. When no gold is found, Kellerman does not believe that Engles does not know where it is and shoots him. In the ensuing fight, Wesson drags the unconscious Blair out of the basement. The burning hut collapses on the others. Carla reveals that she knows where the gold is, but cradling Blair, declares she will never reveal its location, as it has caused too many deaths.
