They say the third time’s the charm, and reformed party girl Kate is hoping that’s true when she becomes the third wife of a slightly older man, Pete. They fell into each other’s arms at a karaoke bar, and flash forward a year later, Kate finds herself with an instafamily complete with three stepchildren and two ex-wives. Diane is ex-wife number one, an intense and overachieving former Olympic athlete and the mother of teenagers Hillary and Warren. She is quick to convey her withering disapproval of Kate. Hillary is not a fan of her new stepmom either, despite Kate’s attempts to win her trust. And Warren may have an erotic fixation on his dad’s beautiful, young spouse. Ex-wife number two, Jackie, is mother to adopted son Bert, and can pull Pete’s strings with her special blend of neurotic, new-ageyness. Kate finds support with her best friend, Meg, a party-hearty singleton.
