The Whispers

We love to play games with our children. But what happens when someone else starts to play with them, too? Someone we don't know. Can't see. Can't hear.

While John Doe continues on his mysterious mission, Claire attempts to hold back his sketch from the other bureau offices while she investigates his identity on her own, Lena is aware and not too pleased that Wes has been speaking with Claire about a case, and Drill continues playing his dangerous game with Minx, Henry and Harper.

John Doe holds Dr. Maria Benavidez hostage as an unknown entity continues to blindly lead him to an undisclosed location, and Claire and Wes further their investigation into John Doe's past whereabouts and begin to uncover what his next target is.

While Minx tries to persuade a disillusioned Henry to play one more game for Drill, the race is on for Claire and Wes to thwart John Doe from causing a major incident that could potentially kill millions of people.

Claire speaks with Sean, who has no memories of her or their life together, and tries to get him to remember something.. anything about his past; Wes has an epiphany and heads back to Mali to take another look at the fulgurite, and Lena keeps a watchful eye on Minx to make sure that her conversations with Drill have ceased.

An astonishing breakthrough is made about Drill while Claire gathers together and talks to a group of children who have been contacted by it, and Wes makes a chilling discovery about Drill's possible mission.

While Wes is meeting with the President about his discovery, Drill targets a member of the President's family; Sean faces possible consequences for his collaboration with Drill; Lena gets help from Minx as she tries to contact Drill.

Claire and Sean find a man who had a dangerous encounter with Drill more than 30 years earlier.

Claire, Sean, Wes and Lena attempt to unravel the past of a man who first encountered Drill over 30 years ago, which could lead to a way to kill it -- before Drill finds a way to murder the man first.

A plan is put into place to trap Drill and attempt to drain away its energy, thus killing it in the process. But if unsuccessful, Drill could seek retribution in a most deadly way.

Thinking they might actually be able to defeat this unseen foe, Wes convinces the President to let him round up all of the children in a protected zone in the hopes that Drill will weaken.

One of the children is taken over by Drill, but not everyone is sure which one it is, leading to confusion and fear.

Drill's mysterious end game is put into motion and the team must do their utmost to stop it before it reaches its final - and possibly deadly - conclusion.
