The lovable animated Welsh firefighter is back in this seasonal tale of ice in the valleys. In 'The Big Freeze', a sudden cold snap in Pontypandy brings busy times for our hero. Young Norman's pet lamb is stricken by the freeze and mum won't have it in the house. A muddle featuring an old electric blanket ensues, whereupon Fireman Sam has to step in and point out the dangers of ageing electric blankets. Other episodes are 'Deepwater', 'Fields of Fire', 'High Jinx', 'Mummy's Little Pumpkin' and 'King of the Jungle'.
