Someone in a quiet, unassuming cul-de-sac was shot dead in the middle of the night. Was it Maggie, the perfectionist wife, or Craig, the husband who can't quite live up to her expectations? When Maggie witnessed a shooting and later testified against a killer set free, the couple relocated, putting new pressure on their already strained union. Maggie is constantly looking over her shoulder. She owns a gun, just in case. Was it Nick, a doctor whose family, especially his wife, Dani, must bear the brunt of his ill temper? Nick is an avid hunter, too, and keeps a collection of handguns. Or was it Julia, a recently widowed grandmother? Her grandson is a troublemaker, someone not above stealing from her purse. His friends are equally unsavoury. Her son buys her a gun for her protection. And then there's Olivia and her husband, Vic, who has been laid off, forcing Olivia to become the breadwinner. Vic is resentful. And depressed. He's started drinking heavily, and has threatened to shoot himself on several occasions. Or it could be one of the newlyweds, Aiden and Heidi, who are already on the rocks. Aiden refuses to stand up to his intrusive mother. When Heidi befriends Julia's grandson, it sets the stage for a major blow-up. Every house owns a gun. And anyone can be the victim, or the killer.
