Ben's school is closed due to a flood warning. This could be a real emergency! At home, Ben and his family start to secure the house against the rising water. But what about the sheep in the field at the end of his garden? The farmer is stuck on his farm and can't rescue them. Luckily, the RSPCA are on hand to help. Together Ben's family and the RSPCA Inspector herd the animals to safety - through Ben's garden! But one little lamb has been left behind. How will they get the animal across the deep water?
