The Mayflower Society is about to hold its annual meeting at Washington DC's swanky gathering place for the elite, the Continental Club. That means Kit Marshall's upper-crust future in-laws, Buffy and Winston Hollingsworth, are coming for a visit.
Annoyed that Kit has not set a date to marry Doug, Buffy wants her to commit to a high society wedding at the club. Kit, though chief of staff for a congresswoman, feels uncomfortable with Buffy and Winston's crowd.
Kit receives an unexpected reprieve in the form of murder. En route to her morning jog, she encounters the corpse of the leader of the Mayflower Society, conservative multimedia tycoon Grayson Bancroft. On the security cameras, no one was seen entering or leaving the club, which means the culprit had to be an overnight guest. Little love was lost on Bancroft, but the police have their prime suspect: Doug's father.
Buffy and Winston, formerly disdainful of Kit's sleuthing, urge her to investigate. With her future in-laws' freedom and reputations at stake, Kit sets out once again to solve a murder mystery, this time aided by her fiance Doug in addition to her friends Meg and Trevor and her dog Clarence.
