Paranoia-fuelled Zack Walker has trouble convincing his loved ones to obey his rules for keeping them out of harm's way.
He's even uprooted his family and headed for the tranquillity of the suburbs. But then Zack stumbles upon a body, and a trail of deceit and murder leads right back to his own front door. Suddenly the 'burbs is not looking nearly so safe....
With a killer roaming around their neighbourhood and Zack's overactive imagination in overdrive, he's sure things can't get any worse. But then another local is murdered - and Zack's paranoid tendencies get him implicated in the crime. To protect his family - and avoid being busted for a crime he didn't commit - he's going to have to override his instincts and track down the killer himself.
