The title Mujeres Que Trabajan translates roughly as Working Women, an accurate description of the film's collective. Spending their days laboring away at a huge department store and their nights cooling their heels in a boarding house, the girls are naturally susceptible to any and all promises of overnight wealth. Curiously, when wealthy Ana Maria (Mecha Ortiz) moves in with them and offers them a huge amount of money, they refuse, preferring to make their own way through the world. Ana Maria's inability to "connect" with the girls causes her a great deal of grief, but at long last they accept her as one of their own. Stealing the film is third-billed Nini Marshall, who wrote all of her own dialogue.
