Charlotte Silver was once a professor until the lack of money points her in a different direction. Greed and anger motivate her to start and run a criminal organization. Its mission is to kill healthy and wealthy older women in hospitals for large sums of money. Charlotte and her team have become incredibly rich working their dastardly deeds with seemingly no repercussions. The killings continue at a convalescent facility known as The Residence near the local university, but it is here where Charlotte's organization hits a snag. When a resident dies of a supposed heart attack, snoopers get curious, and Charlotte is forced to use violence to quiet them. But these snoopers are not easily deterred, and five adventurous seniors now seek to uncover and destroy her evil organization.
