An Argentine who emigrated to the United States finds himself by chance in Argentina for business. There he hires a woman, Paula, who is from a traditional but poor family, and he finds himself falling in love with her.

Luzmila and Peta are two sisters who come from a modest environment and work as housemaids for Alicia and Carmen, two aristocratic ladies of Peru. They are almost considered a part of the families or, at least, that’s what it seems… But one day, as the city is taken over by violent protests, a birthday celebration gathers all the members of both families together. A long-held secret involving both households — upstairs and downstairs — is suddenly revealed, blowing up the bubble of their perfect aristocratic world forever.
