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.

A look back at three First 48 cases where the victims were in the wrong place at the wrong time. In Tulsa, what appears to be a case of road rage turns out to be something else entirely. Then, a man is stabbed to death in his car and Tulsa detectives have a hard time believing his friend's story of what happened. And investigators in Harris County must get to the bottom of a car wash shooting that leaves a man dead.
