The spy is intercepted and killed by Pettrus Baariot, the telegraph operator, who then succeeds in sending a message that saves the Stratiria forces from defeat. For his heroism, Pettrus is promised a promotion, but after his recovery from his severe wounds, he is humiliated through the treachery of Danick Rysson, a government official who desires to marry Floria Natarre, Pettrus' beloved. Bitter, Pettrus listens to the overtures of one of the enemy and steals the new telegraph code.
