 Fred Riordan is an ex-con who is re-arrested less than 48 hours after his release on parole. He served four years for robbery and on his release, seems like a mild mannered man who is intent on making a go of it. He recounts to the warden and prison psychiatrist the events during his two days of freedom as they try to determine what may have caused him to get drunk and break up a bar in his old neighborhood. The psychiatrist is convinced that something in the outside world frightened him and probes to determine exactly what that was. Little do they know that there is something altogether different taking place.
