Line of Fire Description, Courtesy of NBC:
A family of law enforcement agents bridges personal differences and crosses professional boundaries as they tackle cases for the FBI, US Marshals, Secret Service, and Department of Justice. After a seemingly cut-and-dry case turns into a deadly conspiracy, they must use the expertise from a lifetime of protecting civilians and politicians to protect one another and bring the killer to justice … even if it means betraying their sworn code.
