30 years ago, two thieves made off with 500 million in paintings they stole from Boston’s Isabella Stewart Gardner Museum. Neither they, nor their paintings, were ever found. Now, Netflix is hoping the world’s biggest art heist can be their next big hit with This Is a Robbery, a docu-series that gets experts on the cold case in attempt to figure out just what happened. The series will premiere on April 7 and seems very likely to be the next thing everyone’s talking about, so get on board while you can.
