Over 10 episodes,A Plan to Killwill uncover the truth behind vicious killings that have made their way into the press and others thatremain largely unknown.

On the former side is the murder ofAmie Harwick, who had a very successful career as a therapist based in Los Angeles and was also engaged to comedianDrew Careyfor a time.

After having placed two separate restraining orders on her ex-boyfriend,Gareth Pursehouse, he found a way into her home and lay in wait until his moment of attack was just right, murdering Harwick and eventually being arrested for the crime.

The other episodes will bring the true-crimes stories to towns across the United States, where everyday people suffer because of slights they may not have even realized they committed.
