In the near future, Abby Muse flees California to save her youngest son, Dillon, from the Takers, who are federal agents sent to assume custody of all America’s five-year-old children and place them into the government’s elementary school, which they’ve hidden from the public in an unknown location. Not only do the Takers fly hovercrafts in front of thunderclouds and use its lightning as a weapon, they kill to take the children, as they had done to Abby’s husband when he stood in their way of confiscating their eldest son, Ethan. Her only goal is to hide Dillon and somehow hold Ethan in her arms again. In Washington state, Abby meets Doctor Will Henderson, who introduces her to the Underground, a nationwide organization vowing to find the school and discover why the Takers School’s students are being embedded with chips in their frontal lobes and why their memories are altered. What they encounter could end humanity.
