After a distraught and depressed woman attempts suicide, Barnaby Jones is compelled to re-investigate a case in which he may have helped wrongly convict her ex-husband of kidnapping a little boy four years earlier.
Barnaby continues to re-investigate an old kidnapping case in which he firmly believes the wrong man has been put into prison for the crime. But as the investigation deepens, and the murders pile up, Barnaby knows he is close to the truth.
Barnaby is one step ahead of three syndicate hit men in tracking down a witness in the remote mountains in a national forest when one of them fires a shot at him, grazing him in the forehead. The force of the blow knocks Barnaby temporarily unconscious, and when he wakes up he can't see. While hoping J.R. will rescue them both, Barnaby must rely on his wits to try to outwit the gunmen.
