 Josephine is interested in flying (and she s also interested in Slim, the aviator) but her suitor Chubby is afraid of flying and tries to talk her out of going up. But she excitedly accompanies Slim on a flight, and even throws a taunting message at Chubby as they pass him. The next day, when chewing gum salesman Chubby visits the Mexican quarter to sell his wares, his flirtation with a Mexican woman angers her family and friends, and they take after him. Warned by a Mexican boy, Chubby sends Josephine a message seeking help and hides in a shack. Josephine, with the help of Slim, takes to the sky again and manages to scare the angry mob away. But when the excitement is over, she chooses to leave with Slim.
