Wormwood tells the story of Eric Olson’s lifelong investigation into his father’s death. Did he fall? Did he jump? Was he pushed? Was it an accident? A mind-control experiment gone wrong? Was it murder? Was it an execution? To get to the truth, Wormwood also re-enacts the last ten days of Frank Olson’s life. Thus, about 18 minutes into the first episode, Frank Olson is being driven to a lakeside lodge for a meeting with his Fort Detrick and CIA colleagues.
