Great British farcical comedy set in the great outdoors. Sid James and Bernard Bresslaw are the pair of likely lads, although 'lads' might be stretching a point rather, who trick their girlfriends into accompanying them to a nudist colony - but it turns out to be a family campsite. After they are persuaded to stay, 'the boys' manage to find more mischief to occupy them when a coachload of teenage schoolgirls arrives at the site.
