Sherlock and Joan search for a murderer who used poisonous mushrooms to kill a botany professor and a group of the instructor's students. Also, when Joan is disturbed by loud noise next door, she discovers her neighbor, Trent (Richard Kind), is renting out his home through a vacation site that caters to hard pratiers.

Although Finch insists that he no longer wishes to help with new numbers, his interest is piqued when Reese learns that the newest POI is a brilliant college student engaged in a mysterious, life-and-death scavenger hunt. Now he must decide if he can help without alerting Samaritan.

Shaw joins a team of international thieves in order to keep tabs on the latest POI, but an unexpected turn of events puts her in danger of being detected by Samaritan. Finch and Root, meanwhile, undertake a dangerous sabotage mission.

Reese volunteers as an NYPD Police Academy instructor in order to keep an eye on a talented young officer whose suspicious actions make him question her motives. Meanwhile, Martine – armed with information from Samaritan – hunts a member of the team.
