Paris, 1938. A shadow edges over Europe, while in Spain the war has already begun. Cristián Ferrar, a handsome Spanish lawyer in Paris, is approached to help a clandestine agency supply weapons to beleaguered Republican forces and agrees, putting his life on the line. Joining Ferrar is an unlikely group of allies: including Max de Lyon, a man hunted by the Gestapo, and the Marquesa Maria Cristina, a refined beauty with a taste for danger.
