Plot. The young Prince Dimitri is the last of his dynasty; but while he lives and may have sons, the way will never be clear for Prince Karl, the head of the rival dynasty. Three officers of Dimitri's own regiment of Guards have caught him in a death-trap and come to murder him. Dr. Stronetz for the moment saves him by what appears to be a trick. But it is no trick; and the trap closes on the traitors who have set it.
