This time the jokes are really ancient! Roland Crump, and Anna Vooshka are eminent archaeologists excavating a Roman Town that just happens to lie beneath a caravan site at the height of the summer season.
Surrounding the distinguished diggers are holiday pals Ernie and Fred who have their sights set on the local beauty spots - the female campers - and Carry On favourites Joan Sims, Peter Butterworth and Bernard Bresslaw who are on hand to fuel the 'in-tents' humour.
In Carry On Behind, the team leave no stone unturned in their ruthless pursuit of laughter!
