While the conspiracy theory itself might be well-known, the true story surrounding a victim and his family still goes untold. The eerie trailer follows Dr. Frank Olson (Sarsgaard), a CIA bacteriologist, who was poisoned with LSD. That covert experiment eventually lead to his death. The beginning of the teaser looks like any television trailer might, but the interview with Eric Olson, Frank Olson's real son, adds the documentary aspect back in.
