For her second CBS-TV special of the 1974-75 season, Lucille Ball Productions signed Dean Martin to co-star with Lucy, and contracted Bob O'Brian to write the script.  In this Las Vegas-based farce, a new Lucy character is introduced (Lucy Collins), who plans to go see Martin's nightclub act in the desert resort town.  Subsequently, she makes men fall off ladders, botches a series of odd jobs in a casino, and gets chased through the MGM Grand Hotel by a bunch of men she believes to be gangsters.  The hour-long special is reminiscent of a lengthy Here's Lucy or Lucy Show episode.  Variety, however, dismissed the O'Brian script and the entire production as "old hat."  Martin had previously appeared in Lucy's favorite episode of The Lucy Show, "Lucy Dates Dean Martin," which aired on Valentine's Day in 1966.
