Complete story — includes the ending
Root and Reese travel to the remote (and fictional) upstate town of Maple in search of Shaw. The two find a truck with a stretcher and medical equipment inside, leading them to a doctor; who was anonymously consulted for the job, but did not call the police since Maple has a history of job losses for those who ask too many questions. Root and Reese realize that Samaritan is experimenting with Maple as an "ant farm" to study human nature. After kidnapping and interrogating Maple's mayor Leslie Thompson, she leads them to the factory where Shaw was last seen, but Reese and Root instead find a secretary from the stock exchange, one of many innocent people who Samaritan is experimenting on with neural implants. Fusco and Dani Silva (from "Point of Origin") investigate The Machine's next number, one Arthur Weiss, a seemingly unsuspecting citizen revealed as a freelance assassin. They lure him into Silva's home and engage in a fight, with Silva shooting him to save Fusco, thus making her first kill. The Machine sends the team a coded message telling them to stop looking for Shaw. Elsewhere, Shaw is revealed to be alive and in Greer's captivity.
