Highly sought-after young cook Kat Holloway takes a position in a Mayfair mansion and soon finds herself immersed in the odd household of Lord Rankin. Kat is fine with the family's eccentricities as long as they stay away from her kitchen, but trouble finds its way below stairs when her assistant is murdered. Afraid for her life, Kat turns to the mysterious Daniel McAdam for help. Daniel takes a position in the house as a footman and stand-in valet so he can investigate covertly, but Kat cooks up a suspect list of her own.
