In this film, young, headstrong Margaret Harwood (Penelope Ann Miller) is entrusted with a business assignment by her wine merchant father. While taking an inventory of the contents of the wine cellar of a Scottish estate, Margaret discovers an almost-priceless bottle of wine from the "year of the comet." When Margaret alerts her father to the find, he sends his crude assistant, Oliver Plexico (Timothy Daly) to fetch it. Although Oliver and Margaret initially have no great love for one another, they discover that they are forced to work together to keep the wine out of harm's way.
