The series featured an ensemble cast led by Ana Ortiz as Marisol Suarez, Dania Ramirez as Rosie Falta, Roselyn Sánchez as Carmen Luna, and Judy Reyes as Zoila Diaz.

While working for Beverly Hills' most glamorous and powerful citizens, the maids are exposed to and often a part of secrets, mysteries and crimes hidden behind their employers' wealthy facade as well as the closed doors of their homes.

Edy Ganem, Susan Lucci, Rebecca Wisocky, Tom Irwin, Brianna Brown, Brett Cullen, Grant Show, Drew Van Acker, and Nathan Owens feature in supporting roles throughout the series.

[6] The first season premiered on June 23, 2013, and introduces the four central characters of the show: Marisol Duarte (Ana Ortiz), Rosie Falta (Dania Ramirez), Carmen Luna (Roselyn Sanchez) and Zoila Diaz (Judy Reyes), as well as their rich employers in the town of Beverly Hills.

The main mystery of the season is the sudden murder of fellow maid Flora Hernandez (Paula Garces), and the involvement of her employers Evelyn (Rebecca Wisocky) and Adrian Powell (Tom Irwin) in the events leading up to it.

Once an English professor, Marisol takes a job as Taylor (Brianna Brown) and Michael Stappord's (Brett Cullen) maid in order to get close to Flora's old friends and prove her son's (Eddie Hassell) innocence of the crime; Rosie works for actors Peri (Mariana Klaveno) and Spence Westmore (Grant Show), though eventually enters into an affair with the latter; Carmen takes a job for singer Alejandro Rubio (Matt Cedeño) in hopes of him making her a star while dodging the feelings of her co-worker, Sam (Wolé Parks); and Zoila tries to prevent her daughter Valentina (Edy Ganem) from being with her boss Genevieve Delatour's (Susan Lucci) son, Remi (Drew Van Acker).

Carmen briefly acts as Alejandro's fiancé when word gets out that he's gay, but his sudden assassination leads to her taking a job working for Spence, who has lost both Peri and Rosie.

The third season premiered on June 1, 2015, and its central mystery revolves around the return of the Stappords, what they're hiding, and if it relates to the respective deaths of tennis pro Louie Becker (Eddie Mills) and later maid Blanca Alvarez (Naya Rivera).

Four months since Ty's drive-by shooting and Rosie wakes up from a coma, but she's unable to enjoy married life with Spence due to the return of her supposedly deceased husband, Ernesto (Cristián de la Fuente).

Carmen finds work at the Powells and briefly acts as Adrian's dominatrix, while also continuing her affair with married man Sebastien Dussault (Gilles Marini) whose wife (Michelle Hurd) she hopes can make her into a star.

Zoila's relationship with Javier ends when she lies about him being the father of her unborn child, and her friendship with Genevieve falls apart due to her boss' new love, Dr. Neff (John O'Hurley).

The fourth and final season premiered on June 6, 2016, and its main mystery is the sudden murder of Peri Westmore, and the involvement of a cult known as "The Circle" in the events leading up to it.

Zoila has permanently quit being Genevieve's maid following the loss of her child when in labor, but due to the absence of her new employer (Kate Beahan) she's able to masquerade as a Beverly Hills' socialite and land a new man - Kyle (Ryan McPartlin) - who has an extremely close bond with his mother (Stephanie Faracy), the secret leader of "The Circle".

Marisol's book is in the process of being made into a movie which leads her into the arms of studio head Peter Hudson (James Denton), but continues to have lingering feelings for Jesse, who has a fling with Danni (Sol Rodríguez), Carmen's daughter that she gave away at birth and now is starting to build a relationship with.

Richard Burgi, Andrea Parker, Jolie Jenkins, Patrika Darbo, Dakin Matthews, Liz Torres who previously appeared in Desperate Housewives, have guest roles in this series.

In February 2015, it was reported that Glee actress Naya Rivera had joined the season in the recurring role of Blanca; a maid to a seemingly ideal family, who learns of a life altering secret.

Ryan McPartlin will make a debut this season by playing Kyle who is a sweet, sexy — and, most importantly, filthy rich — newcomer who falls for one of the core maids.

In early February, Carlos Ponce was announced to play Ben who is the manager of a famous movie star, but also a dangerous-yet-handsome thirty-something who specializes in manipulating people.
