Ever wonder what happens to those Final Girls?
After the cops eliminate them as suspects, after the press releases their brace-faced, pizza-cheeked, bad-hair-day class photos that inevitably get included on the cover of the true crime book?
After the candlelight vigils and the moments of silence, after someone plants the memorial shrub?
 
For Lynette Tarkington, it's been a support group. Her, five other final girls, a therapist. Close to twenty years. Today's the last day for group, but Lynne doesn't know it yet. It's also going to be the last day for one of the group. And maybe the final day for all of the final girls, because someone's been planning a nasty surprise for them for a long time.
