The Whispers

Something is manipulating the most innocent. In Washington D.C., several kids have been talking about their imaginary friend, Drill. Claire is called in to investigate.

Children continue to make friends with Drill, the entity that only kids can see and hear. Claire and Jessup try to get more info from Minx about but she's reluctant to talk.

Wes and the U.S. Department of Defense look deeper into the events surrounding the children who were coerced by "Drill" to do some unimaginable things.

As the pieces to the mystery of John Doe/Sean Bennigan start to come together, Wes and Claire think that Sean might be involved in planning a nuclear plant meltdown.

Shaken by the nuclear plant disaster, Claire can no longer ignore her growing belief that whoever is influencing them must be otherworldly. Wes analyzes Sean's polygraph results.

Wes transfers the rock to a top-secret government site and hopes that by studying it they will learn more about Drill but Claire thinks they are playing into his dangerous game.

Now that Sean Bennigan remembers everything, he knows he must destroy the rock. However, Wes disagrees and this puts Claire in the middle of the two men once again.

Claire and Sean escape the aftermath of the destruction of the mysterious rock. They meet up with Jessup and Henry who tell them that their attempt to destroy Drill didn't work.

Claire, Wes and Lana are rounded up by Frommer's men while trying to uncover the mystery of how Thomas killed Drill when he was a boy. Search leads them to a mental institute.

Claire, Wes and Frommer go on the offensive to catch Drill and shut off power grids around the city to corner him in an abandoned school where they will wait for him to expire.

Minx passes out and is rushed to the hospital. Upon arrival, Wes finds it filled with ailing children. Maria notices the children all share a "symbiotic link" put there by Drill.

Claire finds that evidence points to Minx being guilty, including an eyewitness account of her murdering Dr. Benavidez, and has no choice but to advise Frommer to take Minx away.

Cassandra is transported to a secure site, where she is interrogated by Wes and Claire. She erupts in a blinding light and it becomes apparent she has triggered the children.
