Faced with the truth behind the disappearances, Bryce, Charlotte, Kyle, Tommy and Will have a choice to make. Meanwhile, while the kids are trying to process what's happened and what they've learned, the aliens return to Earth and start invading and abducting more people.

As the kids search for help and for answers, they soon learn the truth behind the disappearances. But are they ready to believe it?
