What has Mike done?Do they have the wrong man?Overnight, the threats become attacks, and Mike, his wife, and their young daughter learn they aren't safe anywhere -especially not their own home.

He doesn't know who they are.He doesn't know what they want.But there's no time to figure it out - because his enemies have killed before, and he's next.
