An industrialist tries to find an advertising gimmick for his canned meat product "Eat it!". In the fields he finds a savage individual who has reduced himself to two functions only: eating huge amounts of food and making love. So he uses this savage man for his advertising purposes by making the public believe that his meat is an aphrodisiac. Some time later the strange being loses his "gifts". The industrialist tries to replace him, but the incredible amounts of meat he eats turns him into a cow! (Digitmovies)
