Maria spends her daytime sewing and cleaning, while at night she works as a prostitute in Oporto's streets. Years ago her path crossed with José, a married man who became her most faithful client but who couldn't help her to escape the hard life. Today this old prostitute continues showing off her body through the long city's nights, though the clients are almost gone. José is still there, but he failed at what she desired the most: a son. In a very intimate and raw portray of a woman, MARIA disclosures how love and getting older can feels like.

Maria passa o dia a cozer e a limpar, enquanto à noite trabalha como prostituta nas ruas do Porto. José, seu amante e mais fiel cliente, não a consegue ajudar a escapar duma vida dura, e nem dar a esta mulher o que ela sempre mais desejou. Num íntimo retrato, MARIA revela sem medo a crueza do amor e do envelhecimento.
