It all begins when his editor assigns him to look into a mysterious want ad that offers a large reward for information concerning the murder of a policeman who died a decade before. The charwoman behind the ad is the mother of the convict. She is convinced of his innocence and so spent the last 11 years trying to save up the reward money. At first the world-weary journalist disbelieves her, but still, knowing a good story, writes it for his column. The article generates an outpouring of kindness for the devoted mother. The reporter's boss is also affected and assigns the reporter to look deeper into the killing and the trial. Sure enough, the ensuing investigation opens up a major worm can in the police department. Unfortunately, the one cop who could really help him died years before. He meets the actual convict and after watching him pass a lie detector test decides to try to get the young man freed. The murder happened when a policeman walked in on a robbery. The reporter goes to visit the store clerk, a bitter woman who swears the young man was the killer, but the journalist discovers that she has reason to lie. In the end, he finds proof. Using his own ingenuity and modern technology, he is able to prove it and at the last minute during the parole board meeting held to determine the young man's fate, ensures that justice is finally done. The actual reporter, Jim McGuire won a Pulitzer Prize for his investigation of Joe Majczek's wrongful conviction. The film is also titled Calling Northside 777.
