A 911 call comes in on August 22, 2005... Stacey Castor can't get into her bedroom where her husband David has been holed up all weekend. When police show up and break down the door, they find David inside... deceased. Although originally ruled a suicide, Detectives don't take the scene at face value and keep the investigation open. They reach out to get some history on Stacey Castor only to find that her first husband is unable to talk to them, as he has also passed away in recent years. This is only the beginning of the plot twists and turns as a ruthless Black Widow is brought to justice, but not before one more victim is almost taken in her grasps.
