A big freeze has fallen over Pontypandy and with the snow comes lots of trouble!

Sarah and James attempt to take the winning photograph for a competition, but they accidentally cause an avalanche and find themselves trapped in a cave. When Trevor is distracted, showing off to Dilys, he loses control of his bus full of passengers and they find themselves stranded on a frozen lake. Meanwhile Norman and Derek get up to their usual pranks and unknowingly create a giant snowball that starts to roll around Pontypandy.
