Rosie, an ambitious and by-the-books event planner finds herself at odds with her new assistant, who happens to be the son of her boss, on the eve of the biggest wedding of her career.
The Bonneville Hotel is the best kept secret in Mayfair: its art deco suites and glittering ballrooms a former home-away-from-home for royalty and film stars alike. Recent years haven't been kind, but thanks to Events Manager Rosie, the Bonneville is reclaiming some of its old cachet as a chic retro-glam wedding venue.
While Rosie's weddings are the ultimate in romance, Rosie herself isn't; she's focused on the details, not the dramas. But when the hotel owner appoints his eccentric son Joe to the Bonneville staff, Rosie finds herself up against an unprecedented challenge: a rival whose predilection for the unconventional could derail not only Rosie's own career, but the most elaborate, high-profile wedding the Bonneville has ever seen.
