The lives of two strangers, Greg Jenkins and Megan Brighton, become inextricably entangled when they each sign up for a dinner dating agency. Greg's reason for joining has nothing to do with looking for love. His recently divorced sister, Sam, has disappeared and Greg is convinced that Dinner for Twelve, or at least one of its clients, may be responsible.
Neither is Megan looking for love. Although single, she only joined at her best friend Brenda De Luca's insistence. When a client of the dating agency is murdered, suspicion falls on several of the members. Then Megan's friend Brenda disappears without trace, and Megan and Greg join forces. Will they find Sam and Brenda? Or are they about to step into the same inescapable snare?
