Claire and Sean track down a man who had his own deadly encounter with Drill — over 30 years ago.

While Drill loses strength, all of the children he has contacted are becoming ill.  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 wither and fade away.  Meanwhile, one of the team mourns the loss of a love one.
