On their rainy wedding day, Drs. Greene and Corday must fight fate to get to the altar as he overcomes several roadblocks until he is waylaid in the street by a nasty bleeding pregnant woman -- meanwhile, she contends with last-minute details and her feuding divorced parents. Elsewhere, several ER staff try to free themselves from work to attend the ceremonies, including Dr. Finch and Dr. Benton, ever mindful of the irony that he once dated Corday. However, the uninvited Dr. Weaver heads for an out-of-town medical conference and meets a friendly and appreciative man. When a prison van overturns, Dr. Carter tries to save the life of a crushed corrections officer -- and gets some ribbing about his young girlfriend -- while Abby treats a teenaged female prisoner. Dr. Chen ministers to a hypothermic boy found asleep on a frozen field.
