In this first programme of a major new series, three families give up their 21st century creature comforts and time-travel back to face the hardships of life in the Welsh Valleys, 1927. Over the series we discover whether the community will survive without a microwave, mobile, fast car or fast food. Life is already getting tough for the community with the men on first shift at the coal face and the women working round the clock to keep the home fires burning.
