Brenda decides it's high time Jessop Square had its own version of Opportunity Knocks. JessOpportunity Knocks. But what brand new up-to-the-minute fad can she show off? Tony has decided to do kung fu, so Brenda sets her sights on the glories of disco. It's disco v kung fu, but who will come out on top?

For the first time in his life, Tony has got his own way. He's taking the family camping to Wales, and they are not going alone. Tim and Jenny will be joining them for their honeymoon, and they'll be picking up Tony's mother, Mam, on the way. She is a bereaved diabetic with a heart condition. What could possibly go wrong?

They arrive at a deserted campsite, and the worst storm ever to hit the Gower Peninsula is very much on its way.
