Heep is a flying chicken. Heep, Hoop and sister Hop came all the way from Heepland to live with two children, Roger and Penny. Suddenly, all the chickens want to know who is the fastest heep. Heep flies to Roger for help. Even Heep's son, Flyer, is arguing with Hoop's son, Nip, about who can fly the fastest. The Great Heep Race will soon take place.
