This is a static but watchable story of beautiful German spy Florence Vidor, caught between clueless Jack Holt and wily Sessue Hayakawa. The men are trying to protect information about a convoy in the Pacific where a new German submarine force is rampaging -- remember, this is World War One, and the Japanese were on our side -- and Vidor is trying to find out about it, while fighting her feelings as Jack Holt keeps proposing to her. Mr. Holt, in the tradition of all heroes, is a bit musclebound between the ears, while Hayakawa's intelligence shines through.
Despite the motionlessness of the camera, well composed shots and skilled actors keep this one moving along. Charles Ogle is a bit over the top of Vidor's ruthless doctor/spymaster, but in a movie like this, some one has to be.
