Regan Reilly and Jack "no relation" Reilly — head of the NYPD Major Case Squad — are getting married! Arriving at a bridal salon to pick up her dream gown, Regan discovers the designers bound and gagged. Four dresses (hers included!) are missing; a fifth is in shreds on the floor. With just a week before her wedding, Regan takes the case, meeting an unusual mix of brides and grooms-to-be, or not-to-be. Meanwhile, Jack is determined to crack a perplexing series of rainy-day bank robberies — before his upcoming nuptials.
