Detective Regan Reilly and her fiancé Jack—the head of the Special Cases unit of the New York police—are preparing for their wedding. Regan has ordered herself a magnificent wedding dress from two young fashion designers in Manhattan. When she comes to 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 four April brides have disappeared, including the one made for Regan. Shreds of a fifth dress are scattered on the floor. Although only a week remains before her wedding, Regan sets out to solve the case and, as a result, meets a motley company of brides and grooms who are eager—or not so eager—to become spouses.
