Overview
Devil's Island is a 1939 American prison film directed by William Clemens and starring Boris Karloff. This film is notable for Karloff in a then-rare sympathetic role, as opposed to his usual antagonistic characters in horror films. The plot appears to have been recycled from John Ford's The Prisoner of Shark Island, which depicted the true story of doctor Samuel Mudd, who treated the injury of John Wilkes Booth after he assassinated Lincoln.
Plot
For upholding his medical oath in treating a wounded revolutionary, respected surgeon Dr. Charles Gaudet (Boris Karloff) is sentenced to ten years imprisonment to the infamous French penal colony on Devil's Island. It isn't long before he speaks out against the inhuman conditions and incurs the anger of the brutal prison commander, Colonel Armand Lucien (James Stephenson). But when Lucien's daughter Collette receives life-threatening wounds in an accident, the only person on Devil's Island who can save her is Gaudet.
