Watch Online Free on Watchseries. A band of futuristic cutthroats terrorize the skies on board their powerful airship. After bombing a liner and stealing gold bullion from its hold, the ruffians try to escape, facing only Jack Manley, a valiant naval officer, and Marie Thompson, his sweetheart. (The surviving print lacks the story resolution, which apparently ends when the hero and the police rout the pirates and rescue the kidnapped heroine.)
