Our cameras follow Detective Manny Reyes as he investigates the 1990 murder of a Fort Worth, Texas woman. Reyes talks to the woman's two sons, who believe that her husband, Bobby, was the murderer. We then watch as one of the husband's relatives tells Reyes that Bobby has confessed the crime to him. To make the case even stronger, Reyes collects physical evidence that connects him to the crime. Finally, Reyes meets Bobby for a dramatic interrogation. Will he crack and admit the crime--or will he hang tough and deny it all?
