Unjustly condemned to Devil's Island and condemned to death, Dr. Gaudet's life is spared when his surgical skills save the life of the commandant's daughter.

For treating a wounded revolutionary, respected brain surgeon Dr. Gaudet is sentenced to the hellish French penal colony on Devil's Island. There, he rebels against the inhuman conditions and incurs the wrath of the brutal commander, Colonel Lucien. When Lucien's daughter is injured in an accident and only Gaudet can save her, the tables are turned.—Anonymous

When one of his patients is shot trying to escape from police custody, Dr. Gaudet obeys the Hippocratic Oath and tries to save his life, an act for which he is summarily condemned to Devil's Island for ten years. After he and some fellow convicts rebel after a guard's cruelty causes the death of a tubercular prisoner, they are condemned to death. Fate intervenes when Camp Commandant Lucien's daughter is severely injured in a carriage accident. When Lucien realizes that only Gaudet can save his daughter, he offers to trade the prisoner's lives for the doctor's agreement to operate. Although Gaudet saves the little girl's life, the Colonel reneges on his promise by executing the doctor's friend Pierre and condemning the others to solitary confinement. Disgusted by her husband's cruelty, Lucien's wife intervenes by helping Gaudet and his companions to escape.—[email protected]
