Jeff and Karen Gaffney live the suburban dream, Jeff works in HR in the city and Karen works from home as well as looking after their children. The summer finally arrives and the kids go off to summer camp but that leaves a huge gap in Karen's day to day life.
Though her work is busy, she isn't exactly stimulated and once their new neighbour move in to the house across the street, Karen can't help but envy the love the newlyweds appear to share.
Tim and Natalie Jones are the latest additions to the neighbourhood and they're about to add a new touch of glamour to the family friendly street. They're beautiful, sophisticated and educated and Karen is intrigued by them and decides to investigate further. She follows her new neighbour and finally convinces Jeff that there's more to the Joneses that they're letting on. Karen and Jeff break into their house and uncover some missile blueprints, a whole room full of spy gear and personal information on all the people in the street.
After Jeff accidentally shoots Karen with a tranquiliser dart and the pair quickly leave. With their new found information, they're unsure what to do but they know the Joneses are very dangerous people; what the Gaffney's don't know is that they're actually 'good guys' who are hunting some dangerous criminals.
