Garry Kasparov, widely considered the greatest chess player in history, sits for extended interviews reliving his 1997 rematch against IBM's Deep Blue, the machine he had beaten a year earlier. The film cuts between match footage, press conferences, and Kasparov's increasingly agitated accusations that IBM manipulated the games, refusing to hand over printouts of the computer's decision logs and possibly using human grandmasters to intervene between moves. IBM engineers and executives give their side, framing the match as a corporate spectacle designed to boost a sagging stock price rather than a fair scientific contest. Chess commentators and journalists weigh in on the infamous 44th move in game two, the one Kasparov still believes no machine could have found on its own. The film treats the match less as a story about artificial intelligence overtaking human genius and more as one about paranoia, corporate stagecraft, and a champion unable to accept that he might simply have lost.
