Cartoon animation propaganda film promoting National Mark Beef.

John the Bull wins first prize at a cattle show. Title: "The Welcome Home". Back at the farm he is greeted with jubilation and dancing by the other animals. A postman sticks a poster marked, "Your Country Need You" on a nearby tree, before handing a stack of unpaid bills to the troubled farmer. John the Bull learns that the problems are caused by the importing of foreign meat. Title: "Massing the Forces!". John the Bull sends mobilisation forms to all the cows; title: "Forward March!" and then marches them to Trafalgar Square. Posters spell out to crowds lining the street: "National Mark Beef - Is the best beef - Because - It is home killed - Of Choicest quality - And finest flavour". John the Bull addresses crowds at Trafalgar Square, telling them to look for the mark on cows' joints. The crowds string up a carcass of foreign meat from a lamppost, and threaten a butcher selling it. The butcher desperately calls for National Mark Beef, which arrives down the telephone line and kicks out the foreign meat. John the Bull is given a medal. End titles: "England expects every housewife to do her duty and - Look for the National Mark on the Beef. Select Home Killed. Prime Home Killed. Good Home Killed."
