It’s 1916, and the First World War grinds on in Europe. A woman known as Mata Hari is in Madrid, neutral Spain’s capital. She’s there to see an officer serving at the German Embassy called Major Arnold Kalle. Hari in fact hopes that Kalle will be able to put her in touch with Germany’s Crown Prince Wilhelm. What’s unclear, though, is whether this exotic woman is spying for the French or the Germans – or if she’s simply in the game for money. But either way, things aren’t going to end well for her.
