Someone on this quiet, unassuming cul-de-sac will be shot dead in the middle of a sultry July night. Will it be Maggie, the perfectionist wife, or Craig, the husband who can't quite live up to her expectations? They've packed up their two children and fled their life in California, hoping for a fresh start in Florida, only to find the demons of the past hovering on their doorstep. Maybe it will be Nick, a highly respected oncologist, or his wife, Dani, a successful dentist, both with well-kept secrets of their own. Or Julia, an elderly widow, whose troubled grandson has recently moved in with her, introducing unsavoury habits and even more unsavoury acquaintances into her formerly quiet existence. Then there's Olivia and her husband, Sean. Having lost his job at a prestigious advertising agency, Sean is depressed, resentful of his working wife and drinking heavily. He is also prone to increasingly violent fantasies. And what of the newlyweds, Aiden and Heidi, whose marriage is already on the rocks, due to Aiden's reluctance to stand up to his intrusive mother? Matters aren't helped when Heidi befriends Julia's grandson, setting the stage for a major blow-up. A diverse group of neighbours, to be sure. Yet all harbour secrets. All bear scars. And all have access to guns. Not all will survive the night.
