Vengeance Unlimited - Season 1 Episode 2 Victim of Circumstances

FBI catches a suspected serial murderer through identification of his shoes. But after he's been jailed, evidence surfaces that exhonorates the suspect, and claims that the real serial murderer is dead. The FBI profiler, Dr Walker, doesn't want to admits his mistake and buries all evidence. When Mr Chapel finds out about this, he and KC, blackmails the second in command at the FBI profiling division. Chapel then starts to harass Dr Walker over the phone, and teasing him about catching the wrong man. He uses the favour of a client to make it appear that the killer has struck again, just to tick Dr Walker off, but Walker is no fool, and uses his knowledge to profile Chapel.
