Jenny Piper and Arthur Fitton (Hayley Mills and Hywel Bennett) have a boisterous reception in a local bar where they are treated to well-meaning but crude ribaldry. On their first night together before leaving for a vacation in Majorca, the newlyweds are joined by some of the wedding guests who keep the celebration going until dawn. Worse, when the kids eventually get to sleep, their bed collapses due to a practical prank.
