Jack is a retired cop who knows and respects firearms. A recent victim of gun violence, she is confined to a wheelchair, getting physical therapy in a rehab facility, and teaching handgun safety and Second Amendment history to the elderly residents.

It has been said the only thing that can stop a bad guy with a gun is a good guy with a gun. Jack is about to find out if that's true.
