However, at the same time an American supply ship has just been sunk by a German Uboat, although the crew unter their skipper, Captain Spense, escapes in a lifeboat. They incidentally land on Norom, where they discover the High Chiefs camp, and as Seaman Benson does some reconnaissance, he meets Kela, the young female assistant to an alcoholic magician, who tells him that her master was hired by Paj Mub for an exclusive performance in honor of Hitlers upcoming reception. Benson spontaneuously hits upon the plan to impersonate the magician and sneaks into the camp, where Kela instructs him in the use of the magicians props. At the same time, Spense and the rest of his men witness Hitler arriving and disembarking at the island although they do not recognize him from the distance, and decide to investigate.Forewarned by Popoff not to displease the High Chief, lest they would surely not only lose the chance to this contract, but perhaps also their heads, Hitler and his partners meet Paj Mub, who invites them to dinner before he will sign the treaty. However, Benson does his best to crash the party first, by switching the guests wine with kerosene, then Suki Yaki is forced to participate in a magic trunk trick, where he gets knocked out by Kela while his place is unwittingly taken by an indigenous orangutan. Amused, Paj Mub agrees to sign the contract, but as Suki Yaki is supposed to sign before the High Chief, the ape squirts Hitler and Mussolini with ink, prompting Paj Mub to consider signing the treaty the next morning and sticking the ape in the same tent as his foreign guests for the night. ........
