Jeff and Karen Gaffney live a normal suburban life in a quiet neighborhood. He works as a Human Resources executive for a defense contractor, while she stays at home to raise their two children, who are away at summer camp. Life is routine and they've settled into a comfortable if somewhat dull existence. Everything changes when the Joneses move in next door. Tim and Natalie Jones are an impossibly stylish and accomplished couple: he’s a travel writer with stories of exotic locales, she’s a social media consultant, a gourmet cook, and a charity organizer.

The Gaffneys are quickly drawn to their new neighbors, enticed by their exciting lives. But as they become friends with the Joneses, Karen grows suspicious of their perfect facade. Her instincts tell her that the Joneses are not who they appear to be. After some snooping, she discovers that Tim and Natalie are covert operatives. The revelation thrusts Jeff and Karen into an unfolding espionage plot that takes them beyond the safety of their cul-de-sac, turning their ordinary suburban life upside down as they are unwittingly roped into the high-stakes, action-packed world of international espionage.
