Hysterical investigates a mysterious illness that spreads among a group of high school girls in upstate New York. What is causing their sudden, often violent symptoms? Is there something in the water or inside the school? Or is it “all in their head?” The series examines the outbreak in LeRoy, NY, believed by some to be the most severe case of mass hysteria since the Salem Witch Trials. In his search for answers, Dan Taberski (9/12, Missing Richard Simmons, Running from Cops) explores other seemingly inexplicable events of the last few years – CIA officers being crippled with nausea and vertigo; cops OD'ing from exposure to fentanyl – and discovers they’re far more connected than we realize.

From Wondery and Pineapple Street Studios, this 7-part series forces us to grapple with the mysteries of our own minds, and reckon with a contagion that we thought was long dead, but may be the defining disorder of our time.
