A woman named Cleo works as a maid in Sofia’s middle-class house in Mexico City. Also residing in the household are Sofia’s husband, Antonio, their four children, her mother, Teresa, and another maid, Adela. When Antonio returns from a conference in Quebec, it’s clear that the marriage between him and Sofia has become strained, for he complains about every minor slight and lashes out at his loved ones. One day, he suddenly leaves Sofia, who chooses to keep this fact a secret from her kids. As this is going on, Cleo and Adela have some well-deserved time off.
