Q: Prologue: (narrated by Orson Welles) A small airplane with no one on board was flying along the Mediterranean coast near Barcelona . . . Opening shot shows an empty airplane in flight.Credits roll.At night, between the containers on a Naples pier, first we see a man running, then another, staggering, (Gregoire Aslan), who falls and we see a knife plunged on his back. Guy Van Stratten (Robert Arden) and his girlfriend Mily (Patricia Medina) happen upon the wounded man, and at once offer to stay with him and call for help. The dying man says no, no police, as I am dying anyway, in thanks for being good to me, listen, before I die I will give you some names that are worth millions. Find Gregory Arkadin, tell him you know about me, Bracco, and also about Sophie. In the confusion and noise of arriving police, Sophie's last name is garbled as Bracco dies.Guy is arrested for tobacco smuggling and put in prison for three months. Upon his release, he and Mily resolve to find out why that combination of names is valuable.Gregory Arkadin (Orson Welles) is a multimillionaire business magnate whose whereabouts are known, so Guy and Mily proceed to Cannes, but Arkadin has an enormous staff of bodyguards in charge of keeping riffraff away, so Guy can't get to him. Guy gets lucky as someone points out Arkadin's pretty daughter Raina (Paola Mori) to him. As he approaches, she is talking to her constant companion, the Marquess of Rutleigh (Jack Watling) and he says he is afraid to meet her father. Guy politely interrupts the conversation saying he would love to meet her father, and his daring strikes a chord with her, although she rebuffs his advances and warns that she is constantly watched by a large team of her father's employees.Guy has a conversation with Mily, telling her he will follow Raina and make advances to her in an attempt to get to Arkadin. Mily is a voluptuous cabaret entertainer who finds gigs easily, so she will try to become an entertainer for Arkadin, who throws big parties all the time.Guy keeps tailing Raina, finds out she will be driving to Spain, and persists in talking to her until she lets him ride along. On the ride, he is charming and she begins to fall for him.At their destination [Segovia], where Arkadin resides in the spectacular castle [the Alcazar], Guy manages to continue courting Raina while seeing the sights and observing a night parade of black-hooded men doing penance. As he kisses her and she warns that her father will destroy him if he is proved a fortune seeker, he vows he will never ever ask her to marry him. This enhances his attractiveness to Raina.Mily, meantime, sees enough that she feels jealous. If Guy is trying for a relationship with Raina, she will try for a relationship with Arkadin himself.Soon after at a masquerade ball at the castle, Guy enters as a guest and Mily has wangled a singing gig. As Guy enters, the camera follows him and the scale and magnificence of the party are a shocking display of wealth.Guy finally meets the mysterious billionaire Gregory Arkadin, and after a few remarks Arkadin leads him into Raina's cavernous bedroom to talk. He tells Guy he loves his daughter intensely and will do anything to protect Raina from unscrupulous, shady suitors. He shows Guy a dossier on his life, labeled Confidential Report, where Guy's many previous run-ins with the law and other unflattering facts are detailed. Guy is not intimidated but challenges Arkadin instead, claiming that if someone were to investigate Arkadin in a similar way, plenty of dirt would show up, and he himself would not look good.After an instant of reflection, Arkadin offers Guy a deal, that he investigate Arkadin's past and prepare a confidential report on him. Arkadin claims he had amnesia and knows nothing about his own life up to the time when he found himself wandering in Zurich during the winter of 1927 carrying a briefcase with 200,000 Swiss Francs.
