In Beverly Hills, whoever "has the dirt" holds the power. In some of the city's wealthiest families, that power belongs to a close-knit group of maids who have ambition and dreams of their own. The maids are brought together by their jobs, life struggles and the upstairs-downstairs universe of their employers. Rosie, Carmen, Marisol, and mother-daughter duo Zoila and Valentina are the women who turn to one another for support when times get tough, including when fellow maid Flora is found murdered in her employers' home and when problems pop up in the maids' romances and personal lives.
