Calley is training the Trainees for their Rescue Badge. Brewster and Zephie are practising using the crane car, and Zephie falls over, pretending to be hurt, but Brewster doesn't control the crane properly, and goes back to the depot sad. Chatsworth is on the mainline and his hopper brakes seize on a hill, and Brewster is the only one who can help - and rushes to Chatsworth's rescue with the water car.
