Tres de cara a Oriente

This movie looks like it's an earlier version of the Boris Karloff movie "British Intelligence" which was released in 1940, ten years after this one. The Karloff movie was pretty good. In it, a nurse is sent to England to infiltrate the household of a British Cabinet member during the War and she is to make contact with the mysterious "Strengler", who has successfully smuggled information to the German Army about Allied troop movements before the British army even gets a hold of it. Over the course of the film, the nurse/spy must keep her true identity under wraps while spying, but then it turns out that everyone's loyalties may not be to whom they were introduced as being loyal to. While the suspense isn't as taut and thrilling as todays thrillers, it's a competent spy film set during WWI.---and these actors were actually British.
