It's kill or be killed in America.
A young man beats his mother half to death. A girl burns her teacher alive and films it. America is imploding under the influence of 'X', a conspiracy theorist radicalizing innocents on the Internet.

As civilians on the street open fire, Wren's only hope is to hunt down and kill X before the country rips itself apart.
But X could be anyone, even someone Wren already knows...
