The Bonneville Hotel, Mayfair, used to host movie stars but recent years haven't been kind. However, thanks to the organisational genius of Rosie Macmillan, Events Manager, it's reclaiming some of its former glory. While Rosie's weddings are the ultimate in romance, Rosie herself isn't. Her focus is fixed firmly on the details. But when Rosie is forced to collaborate with the Bonneville heir, Joe, her career and her love life are turned upside down.
