The new Belmarian ambassador in Washington, Magnus Anderson, cares little for childish festivities and intends to spend less then his disgraced predecessor, but the embassy has to be decorated for the annual royal charity benefit patronized by queen Therese. Professional event decorator Emily Barnes hopes this prestigious gig will finally launch her small firm big time, and wriggles her 'tastefull excess' style passed his excellency's objections by confronting him with expectations among US public and, crucially, press. To Magnus's devoted career mentor Arvid's surprise, Magnus turns to both the ornate benefit concept and the foxy decorator herself, who also wins his kid daughter's heart.
