Patients in search of a miracle cure end up in critical condition. The race is on to find out what went wrong before more people get hurt. The trail leads back to a medical company with slick marketing and a charismatic CEO. And to a multibillion dollar stem cell industry where greed and desperation collide. Laura Beil, the award-winning host and reporter of “Dr Death,” returns for this six-part investigative series from Wondery, the makers of “Dirty John” and “The Shrink Next Door.”
