The Prisoner of Shark Island

Dr. Samuel Mudd (Warner Baxter) is arrested for being an accomplice to the assassination of Abraham Lincoln (Frank McGlynn Sr. ) when he unknowingly aids an injured John Wilkes Booth (Francis McDonald) following the shooting at Ford's Theater. He's sentenced to life in prison and sent to a treacherous penal colony on a remote island in the Dry Tortugas. But when yellow fever breaks out on the island and strikes the prison's doctor, Mudd's medical training becomes invaluable.
