'A fun storybook for children, and a way to explore friendships and jealousies.' Baby Magazine Max Tractor and Dougie Digger are vehicle cousins. They both show off and pretend to the other that their respective jobs are better and more important. In reality they are jealous of one another: Max Tractor wishes that he could be laying foundations for a huge building or clearing the earth for a motorway, and Dougie Digger wants to stay in the same place everyday and have one person to look after him. Through the exciting drama of a rainstorm, when a river bursts its banks and the fire chief calls the machines to the rescue, things begin to change radically and major differences become forgotten as the machines all pull together. But will they save the day?
