When there are no witnesses, homicide detectives face an uphill climb to find the truth. First, detectives in Cincinnati come across a bizarre homicide at an apartment fire. Then, in Memphis, solving a preacher's murder hinges on a single fingerprint. And a Tulsa woman found dead leaves police a clue that might solve her own murder.

Three stories from The First 48 where a plan proved deadly for unwitting victims. In Dallas, a man is lured to his death in an abandoned apartment; a homeless man in Miami is brutally beaten with a rock; and a Tulsa woman's plan to help her sister goes horribly wrong.
