Kate Klein is a feisty, charmingly insecure Connecticut housewife who trades in a life of late-night karaoke sing-a-longs and West Village brunches with her best friend Janie for a world of mini-vans and Mommy and Me pilates classes. Life in Upchurch, Connecticut, heats up when Kate discovers picture-perfect wife and mother Kitty Cavanaugh dead on the pickled maple hardwood floor of her recently remodeled kitchen. A former chronicler of celebrity gossip, Kate takes it upon herself to solve the mystery of Kitty's murder and the disappearance of Lexi Hagen-Holdt, another Upchurch supermom. Along the way, the mysteries and disappointments in Kate's personal life begin to unravel, including her marriage to the kind-yet-uptight Ben, and her unresolved crush on Evan McKenna, a former neighbor with whom a one-night tryst ended in disaster.
