The English admiralty is concerned when several cargo vessels transporting troops are mysteriously destroyed near Gibraltar. The intelligence services are called in to investigate this worrying incident, hoping they can act in time to prevent a recurrence. Frank Jackson, a lieutenant in the maritime regiment that is stationed in Gibraltar, passes his spare time in Tangiers, his main interests being poker and a cabaret singer named Lola. Despite the advice of General Maxwell and the friendly interest of the general's daughter, Cathy, Jackson allows his gambling addiction to get the better of him and he ends up losing a huge sum of money. Lola offers Jackson an easy way to clearing his gambling debts, by photographing some British military documents for an interested party whose name cannot be disclosed. What Jackson doesn't know is that Lola is not only a cabaret artiste, but also a member of a spy network managed by the ruthless Elinor Van Berg and her sinister accomplice Paoli, their cover being an exclusive beauty parlour. Although Jackson is at first disgusted by the deal he is offered he agrees to go along with it. He intends stealing the precious documents at a ball hosted by General Maxwell...
