Things get complicated for Reese and Finch when the machine names Detective Carter as the latest person of interest.

When the machine names the dons of New York's crime families, Reese and Finch suspect that Elias is targeting his competition.

As the POI team seeks justice for one of its own, Finch realizes one of his team members may go one step too far, in order to end the war with HR. When The Machine singles out one of criminal organization HR's key players, the number may be up for corrupt NYPD Officer Patrick Simmons, in the conclusion of a three-episode event.

The POI team's war with HR nears a boiling point when Finch receives 38 numbers at once from The Machine. He discovers they are connected to an unknown player who is inciting an all-out war between the crime organization and the Russian mob. Meanwhile, a window into Carter's past is seen through flashbacks with her son's father.
