A nearly flawless museum robbery, a missing million-dollar necklace, a stalled investigation. For the victim of the crime, the situation calls for desperate measures, and spunky 72-year-old Pen Fitzpatrick isn't going to sit by and do nothing. When the police have a dozen excuses why they can't solve the crime, Pen does the only thing she can do—gather a group of friends to help catch the crooks and steal back the necklace. They call themselves The Heist Ladies. It becomes apparent the thief is a master con man who is likely working with an international theft ring. The chase takes the Ladies far from home and into elegant European enclaves as they attempt to face him down. Close calls and near misses—it's never quite certain whether the women will be able to pull their own spectacular heist and see justice done.
