Little Blue Truck is a friendly vehicle who happily greets all the farm animals he passes with a cheerful 'beep!' His kindness is contrasted with a big, important dump truck who rudely rushes by. When the dump truck gets stuck in the mud, he learns that being kind and having friends is more important than being big and fast. With help from Blue and all the animal friends, they push the dump truck free, teaching a valuable lesson about friendship and teamwork.
