CARRY ON BEHIND: Anna Vooshka (Elke Sommer) is a Russian archaeologist who has come to England to assist Ronald Crump (Kenneth Williams) and his team of students with an excavation. The place they start digging is a British caravan site and it is the height of the season. Holidaymakers interact with the diggers with hilarious results!  CARRY ON ENGLAND:  Captain S. Melly has been sent to a coed air defense base. His mission? To instill a sense of order in the troops, who are more concerned with capturing the opposite sex than the enemy. His plans for discipline do not go down well with the members of the crew, who do as much as possible to sabotage his efforts. Meanwhile, German planes are coming into view.
