The Twilight Zone #10
When Private Investigator Ben Chambers was hired to investigate a murder that took place several years earlier, he never anticipated that his inquiry would lead to the seemingly impossible: to penetrate the veil of time and see the murder happen right before his eyes. Now that he knows who committed the crime, a larger question makes itself apparent: can he stop it from happening? Can he save the life of a young man who didn't deserve to die? Or does the timestream prevent such things from ever happening? The answer to those questions of the past will forever alter Ben Chambers' future.
