Betty Stanhope, the beautiful bride walked down the aisle with head bowed in sadness and despair. Just as the minister started to speak, Betty looked at her bridegroom and then fell to a little white heap upon the floor. They took her to an anteroom where a physician proclaimed her fit. While they prepared to resume the wedding, Betty fled out the back door (the exit of the title), and thus starts the chase. Betty knows no one she can turn to, so must decide which strangers to trust. Thus an exciting adventure ensues.
