The families add preparation for the final concert to their exhausting daily life. As the Coal House community thinks about its goodbye to life in 1927, will the children be saying goodbye to the pigs and the mums goodbye to the tin baths? The drama shows no sign of stopping in the Coal House! As the experiment reaches its final week, the Cartwrights, Griffiths and Phillips families prepare to return to normal life. Who would have thought that three weeks in a Coal House could have created so many new friends, so much fun and so much pain?
