The film traces the story of
Sam Sheppard (George Peppard), an Ohio doctor wrongly accused of murdering his wife in 1954. As the film begins, a dying Dr. Sam gasps “I know who killed Marilyn.” Sheppard is a successful osteopath in Cleveland working at the family clinic. He has an attractive wife Marilyn and a nine-year-old son. His idyllic life comes to an end one July morning when the police are called to his home after he reports an intruder attacked him and murdered his wife. The case and the ensuing trial get nationwide publicity. Despite an able defense lawyer, Sam is convicted and sentenced to life imprisonment, never ceasing to proclaim his innocence. He is released after ten years through the efforts of his brilliant new young lawyer F. Lee Bailey and given a retrial. Bailey's aggressive defense overwhelms the prosecution and Sheppard is found not guilty at last; however, his life afterwards is not happy. He remarries soon after getting out of prison but it ends in divorce and he is sued for malpractice after regaining his medical license. Desperate to make a living he becomes a small time professional wrestler. The strain of his never-ending ordeal wears on him and he turns to alcohol. He dies a broken man at 46 of a liver disease. As the film ends, a narrator notes that the murderer has never been found and that “the rest is mystery.” ==Cast==
