The night before her wedding, in the middle of the rehearsal dinner, interior decorator Keeley Murdock finds her fiance and her maid of honor in a compromising position. Keeley throws the hissy fit to end all hissy fits and storms out. Now she has to deal not only with a broken engagement but also with "financial blacklist" in a town financially obligated to her ex's family. Rescue comes in the form of the new owner of a local bra plant, who hires Keeley to redo the antebellum mansion he's bought for the woman of his dreams-someone he's never met. Only a designing woman like Keeley can revive her business, give her ex-fiance the comeuppance he deserves ... and ride off into the sunset with a man who drives a vintage yellow Cadillac.
