In the Top-Secret town of Blackwoods, Wyoming, a group of young teens desperately tries to warn military authorities about a mysterious 'Fatal Error' that will enable a malicious artificial intelligence to take over the world. Ethan Tate and his Team Blackwoods squad have had to save the world before -- though they were the only ones to know about it -- and they're hoping they don't have to do it again.
But when the military gets their warning, they put the town on lockdown, and then life at Blackwoods begins to get truly bizarre. The adults in the town start acting very strangely. Have the machines been unleashed upon the town once again, though this time in a most insidious and all-too-personal way? Could all the kids' parents possibly be robotic replicates?
Ethan and his team, along with a most unlikely ally, must find a way to turn back this latest existential threat to humanity...and survive some really awkward family time in the process.
