In the spring of 1958, Desi Arnaz signed a multi-million-dollar deal extending the hour-long "Westinghouse Desilu Playhouse" anthology series (including what would later be dubbed "The Lucy-Desi Comedy Hour") for two more seasons, sponsored by the home appliance division of the Westinghouse Electric Corporation. To promote the relationship between Westinghouse and Desilu, Lucy and Desi appeared in this film that was shown to Westinghouse dealers across America. A special Desilu Studio tour is included as well as the Arnaz's plans for their new shows.
