The big day has finally arrived, Scrapper (a dump truck) is going to work with the big trucks at the recycling yard. When he volunteers his services, he is told by the other trucks that he is too small and they reject his attempts to help. Sadly, Scrapper heads for the front gate where he runs into wise old Gramp Truck who suggests that one day Scrapper will find his own very special skill. Gramp Truck was right! His opportunity finally arrives when the key to the gas pump has fallen into a scrap pile and all the big trucks are running out of gas! Since Scrapper is small he easily gets the key and saves the day! Scrapper is a hero, but more importantly, he has found out that there is a special role even for a little truck like him.
