Detective Regan Reilly and her fiancé Jack, head of the New York Police Department's Special Cases Unit, are preparing for their wedding. Regan ordered a stunning wedding dress from two young fashion designers in Manhattan. Arriving at the salon to pick up her outfit, Regan discovers that the premises have been broken into, the designers have been tied up, and the dresses of the four April brides have disappeared, including the one made for Regan. Pieces of the fifth dress are lying on the floor. Even though her wedding is only a week away, Regan takes on the case and ends up meeting a motley crew of brides and grooms who may or may not be eager to be married.
