Brigadier Rayne deploys his charity campaigns with military expertise but little monetary success until Nan is passed a mink coat by a crook on the run. This inspires the amiable aristocrats to become modern Robin Hoods, and soon they are running a meticulously organised receiving system for stolen furs, giving all their profits to charity.
