A docu-investigation into the death of CIA scientist Frank Olson (Peter Sarsgaard) in 1953, whose fall from a 13th story window in a New York City hotel was ruled a suicide, as seen through the eyes of his son Eric whose own inquest, carried out at his own professional peril, reveals several conspiratorial and sinister layers. Errol Morris' mini documentary series is highly effective, sorrowful and scary but probably would have worked better if the live action bits were cut (though Sarsgaard's emotiveness is generally compelling) and the material was presented as a usual Morris production.
