Storyline

The first act following the Machine and Samaritan's cold war summit, which ended in a standoff, is that Samaritan starts to take the market down by crashing the New York Stock Exchange. Samaritan's plan entails a few small rebounds to prevent the fail-safe system from kicking in. Reese, Finch, Root and Fusco know that the best way to combat this take down is not to deal with anything on the market floor, where the minority of trades are actually made, but to deal with the server in the Exchange's basement, the server which processes the vast majority of trades. Shaw is not with them as she still needs to hide from Samaritan's cameras. As such, Shaw has her own task off site. Both the foursome and Shaw's tasks end up not being as straightforward as they would have liked, each placed in a precariously life threatening situation.

Goofs

While Harold is teaching the machine chess and is talking about the history of the queen and its use as a sacrifice, he forces the machine's queen into a position where he can take it with his rook, but then when the camera enters slow motion when he makes his move, it shows him taking the machine's king instead, despite none of his pieces having been in a position to do so. Furthermore, the king is never actually taken in chess, because if it's in a position where it could be taken (check) then the player is required to remove it from danger, either by moving it or by blocking the piece threatening it. If it's impossible to get the king to safety, then the game is over without the king ever actually being taken (checkmate). See more »

one of Nolan brother's masterpiece...well written, well played.
7 January 2015 | by nalcacimuratSee all my reviews

After i watched the episode i directly checked the writers and the creators. i did not know till then that this show's creator is of one of Nolan brothers. the younger brother .. the writer of Memonto... just brilliant... i watch so many maybe too many TV shows in these days but i have to admit this episode was one of the best i have ever watched. well they mixed up who is carrying the bag but that is OK i guess. the chess game lesson was great.. and we saw how Harrold thought moral values to the Machine... well written well played. big surprise at the end...i wish i can learn at least whose idea was this story... and i have to say it was brilliant. i enjoy the show. Thank you guys... i gave 10 pout of 10.
