A fitness instructor is placed in Bilko's platoon. To get rid of him and to make some money, Bilko tries to get him cast in a Tarzan movie. To do this, Bilko tries to fix it so his man wins the Mr. Universe contest. First step: he hires a woman ('Lucille Ball' in a cameo appearance!) to scream when his man goes on stage. When this fails, he dresses Doberman up in a gorilla suit to fight his "Tarzan". Col. Hall sees the "gorilla" and soon has the whole camp hunting for him.
