Wes meets with the President of the United States to discuss what his team has discovered about a mysterious object that may pertain to Drill. Meanwhile, Sean faces a possible prison sentence for his collaboration with Drill, and Lena attempts to communicate with Drill, with the help of daughter, Minx.

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.

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.

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.
