The series follows the lives of five Beverly Hills Hispanic maids as they navigate through the messy lives of their wealthy and snobbish employers. Rosie (Dania Ramirez), a single mother who left her son back in Mexico when her husband died, works as the housemaid/nanny for a pair of self-absorbed and successful actors, Peri and Spence. Aspiring singer Carmen (Roselyn Sanchez) hopes that her new pop star employer Alejandro can help kick start her career, but Odessa, his very loyal and humorless Russian housekeeper and her boss, will stop at nothing to stand in the way of her dreams. Zoila (Judy Reyes) is the senior maid for Genevieve, a co-dependent, drug-addicted, emotionally unstable wealthy woman. She works alongside her teenage daughter Valentina (Edy Ganem), who has a crush on Genevieve's son, Remi. Newcomer Marisol (Ana Ortiz), whose appearance, knowledge and lack of a Spanish accent does not fit the description of the four aforementioned maids, is hired to clean the home of Taylor, the insecure second wife to a wealthy man, named Michael, whose ex-wife is stalking him. The maids turn to one another for support when their friend and fellow maid Flora (Paula Garcés) is brutally murdered at the home of her employers, the shallow and secretive Evelyn and Adrian Powell, at the biggest society event of the year just moments after she was supposedly raped by Adrian, which Evelyn believed was an affair and blamed Flora for having seduced Adrian. A young waiter is found holding the bloody knife used in the killing at the scene and is arrested, but Flora in actuality was killed by another unseen person after she wrote a letter accusing the person of the crime. It is revealed at the end (unknown to both the other maids and their employers) that Marisol has infiltrated this inner high society circle to find out who set her son (the waiter) up. The women turn to one another for support when their friend and fellow maid Flora is brutally murdered.
