Lion-tamer Floyd Hilston is drafted into the Army. Not wanting to leave his pet lion, Fearless Fagan, he keeps him the woods near the base. One afternoon he and Fagan are discovered by actress Abby Ames, who is playing a show at the base. She guides the Army to Fagan, but they think it's a publicity stunt and tow Fagan and his cage to the base. After some misadventures, Fagan has to be transferred back to the circus, but he attacks a cruel lion-tamer during the transfer and is wounded. Fagan escapes into the forest, where he is sought by Floyd and Abby.
