The film features the antics of a society of
cockroaches in a
Mexican café in the absence of its owner. The owner Manuel is reportedly "off to the
bullfights". The film opens with an instrumental of the title song, but interrupts the song with a solo performed by the
gondolier cockroach hero. He sings the 1926
John Stepan Zamecnik-
Harry D. Kerr composition, "Neapolitan Nights". The title song begins again and is interrupted with a solo by a cockroach parody of
Rudy Vallee. He sings the
Al Dubin-
Harry Warren song, "Sweet Music" from the 1935 Warner Bros.
film of the same name. The scene shifts to a rendition of the title song by a cockroach chorus. They are performing as the background singers to a lady cockroach, who performs as dancer. Her "red velvet gown" consists of a scarlet meat frill. The rest of the film is devoted to the attempts of a
parrot to make off with the cockroach heroine. His plans are foiled by the hero. ==Home video release==
