Fatty (Roscoe Arbuckle) and Mabel (Mabel Normand) are a married couple visiting the Exposition. Fatty gets in trouble by flirting with a passing woman (Minta Durfee) while Mabel shops. He chases the woman into a hula pavilion and makes approaches to the dancers. He is accosted by both Mabel and the woman's husband; eventually the police are called to straighten the whole thing out.
Arbuckle and Normand followed the Keystone tradition of showing up at an actual event and using that as background for a largely improvised film. The event in this case was the Panama–California Exposition, held in Balboa Park in San Diego, California, in 1915–1916. The film is 14 minutes long. It was released on January 23, 1915.
