In 1971, Cleo (Yalitza Aparicio
) works as a live-in housekeeper for a middle-class family with four children in a neighborhood known as Roma in Mexico City. Treated at times as a beloved member of the family and at other times as an outsider, Cleo loves the children, but has to deal with her employer Sofia's (Marina de Tavira
) frustrations, as she deals with a husband who's a philanderer, who eventually leaves her.
Meanwhile, there is student unrest in the city, making the streets somewhat dangerous to navigate, and an impending earthquake.
